Introducing the MASTER PUSUIT series 1000-watt CMH Grow Light System: Industrial-Grade power with dual 500-watt Ceramic Metal Hallide lamps is the most powerful CMH grow system on the market. This fixture delivers DEEP canopy penetration with broad-true full horticultural spectrum from top to the very bottom.

Offering unbeatable yields and unmatched quality potentcy. Focus-designed for specialty flowering plants: Bio-engineered to replicate an ahrness the full brilliance of the sun. Enables growers to mix spectral color levels for optimal full-phase broad spectrums of their choice to provide maximum development for each stage of growth from veg to flower. Adjusting specific spectrum color levels creates unique recipies for maximum cannabidol and terpens quality.

Unparalleled efficiency generates higher quality yields with LESS electrical consumption reducing bottom-line production costs. Our digital ballasts tested 30% more efficient than standard magnetic ballasts producing more lumens of ligh per watt of consumed energy. Our ballast controlled circuit breaking system is nonexistent in competitors ballasts. The most efficient full-dimming ballast offering ultimate control of spectral output

"NO FLICKER" ballasts automatically adjust output frequnecy to maintain constant output. Smart built-in sensors & Network Communication offer full open Circuit Protection, Short Circuit Protection, Under Voltage Protection and Over Temperature Protection.

Cool-Running lights reduce over-heating with open-air reflector digital ballsts in case design utilizing unique passively cooled engineering without the need of internal fans for complete silent operation.

Utilizing twice the amount of photon flux output (2000 umol/s) than the GC-500w CMH lamp, this new innovative technology provides the same intensity but with a full par spectrum that will cater to your plants’ specific needs by allowing you to customize your spectrum while using a wide variety of lamps, such as the 3k and 3k-R.

This next generation technology has increased performance and overall reliability for a lighting system you can count on.


Unbeatable Yields & Unmatched Quality

Grower's Choice Master Pursuit 1000W covers all your lighting needs. These fixtures come shipped with your choice of bulb for the spectrum of light that you require. Available in 4 color temperatures.

3,100K

Full Phase

3,000K-R

Red Enhanced

4,200K

Day Light

10,000K

Finishing

3,100K - Full Phase

Grower’s Choice 3k-CMH lamp utilizes a full phase spectrum that is designed to be used in all stages of growth but optimized for bloom. With a Color Rendering Index of 90 the GC 3k spectrum is very close to natural sunlight but with modest blues, extra red and UV light to serve your plants photosynthetic needs during the flowering phase increasing yields and resin production.

3,100K-R - Red Enhanced

Growers Choice 3kr-CMH lamp is tailored specifically to enhance bloom production through the discharge of intensified red shift photon dispersion, which plants need to promote heavier yields and additional UV light to facilitate terpine and resin production as this is a plant’s natural response to protect itself from UV radiation.

4,200K - Day Light

4K CMH: Grower’s Choice 4k-CMH Daylight lamp is the best option for hearty vegetative growth leading to a healthy bloom phase. With a Color Rendering Index of 98 and intense full spectrum the Grower’s Choice 4k lamp provides near sunlight photon output. This leads to healthier and more robust vegetative growth.

10,000K - Finishing

Grower’s Choice final phase 10k-CMH finishing lamp should be used during the last week to two weeks before harvest and is specifically designed to emit photons mainly in the ultraviolet 350-425 nm wavelength. As high amounts of UV light cause damage to plant cells, plants compensate in order to protect itself and facilitate reproduction by releasing more resinous oils which translates into a higher quality yield


Upgraded Design

The Master Pursuit line utilizes an updated horizontal case to reflector design which accommodates more canopy space.

This new case design is reinforced to protect the fixtures internal components and employs heat sinks with greater surface area, translating to better heat distribution, providing further protection, longer fixture life and better efficiency performance.

  • Clips: Improved ceramic lamp clips keep lamps secure, last longer than plastic clips and redistribute heat better.
  • Lamp Catch: Innovative safety device prevents damage due to dislodged or improperly installed lamps.
  • Level: Integrated bubble level provides a visual reference to verify horizontal mounting consistency.
  • Reflector: Redesigned reflector provides greater heat redistribution, improves cross lighting and PPFD.
  • Cords: Uses quality hard wired power cords with M25 connectors provide IP65 water resistance.
  • Dual Ports: Two receptacles for the master controller eliminate the need for split devices or adapters.

Features & Benefits

AI Ignition Control

This revolutionary feature, unique to our products, makes GC Series Digital Ballast the safest and most reliable ballast when used in automated multiple lamp applications. When multiple units are connected to the same mains circuit, our integrated Ignition Control software will completely balance the electrical draw by igniting one lamp at a time to prevent electrical surges and spikes that can overload the mains circuit and trip circuit breaking systems. For further efficiency, this feature is activated alongside our 'Soft Start Technology'.

Soft Start Technology

Soft Start Technology prolongs lamp life by stopping current rush to the lamp and preventing lamp overload. When the ballast is started from cold there will be a 3 second fixed delay before ignition. After ignition there will be a series of random 0-2 second delays before full brightness is reached after approximately 3-5 minutes. SoftStart Technology is also activated when increasing and decreasing power to the lamp using the 'Smart-Step' feature.

Re-Strike of Hot Lamp after Mains Failure

The GC Series Digital Ballast uses a timed re-strike system that prevents the ballast from re-striking a hot lamp after a power failure. If a hot lamp is detected, the re-strike will be delayed for 60 second intervals until the lamp has cooled sufficiently to be re-ignited. Re-ignition is then controlled by 'SmartStart Ignition Control' and 'Soft Start Technology' software.

Lamp Compatibility

The GC Series Digital Ballast is suitable for use with all good quality HPS, Metal Halide and Ceramic Metal Halide lamps. For a guaranteed perfect match and the best results we recommend Grower’s Choice horticultural lamps. Grower’s Choice lamps are optimized for use with high efficiency electronic ballasts with adjustable output.

Full Circuit Protection

The GC Series Digital Ballast uses a sophisticated software controlled circuit breaking system that is not seen in other manufacturer's ballasts. The system protects against a series of faults including: Open Circuit Protection, Short Circuit Protection, Over Voltage Protection, Under Voltage Protection and Over Temperature Protection. On Ignition the ballast performs a 3 second test of the circuit and in the event of a fault the ballast will go into protection mode to avoid damage to the ballast and lamp.

High Energy Efficiency

The GC Series Digital Ballast is up to 30% more efficient than standard magnetic ballast producing more lumens of light per watt of consumed energy. Efficiency does not diminish and is maintained for the entire life of the unit.

Automatic Frequency Adjustment

The GC Series Digital Ballast automatically adjusts its output frequency to maintain a constant output regardless of input power fluctuations and ageing lamps. This also prevents 'lamp flicker'.

Running Temperature

The GC Series Digital Ballasts' unique case design acts as a superior heat sink making the ballast extremely cool running without the need for internal fans.

RF Shielding

The GC Series Digital Ballast has superior RF Shielding with Total Harmonic Distortion (THD) of less than 10% meaning it will not interfere with television or radio equipment.

Silent Operation

The GC Series Digital Ballast has no noisy internal fans and is completely silent in operation. You'll be able to hear how happy your plants sounnd with how quiet this fixture is.


Grower's Choice Master Lighting Controller

Grower’s Choice Master Lighting Controller enables the grower to control up to 200 fixtures.

This dual-channel controller allows daisy chaining up to 100 fixtures per zone. Enabling complete control of your growing environment with timed on/off switching, sunrise/sunset, and precise temperature readings with dual thermal probes and thermal-threshold auto dim-shutdown for additional protection.

Perfect! Read this for large size
Special Size Type: Standard, Size: Large, Color: (New) Rinse
Man, let me tell you when I say I've never been so nervous about an amazon order before. I've wanted one of these for a long time but the reviews had me a little shook. I'm 6' tall and 210lbs. I'm definitely not fat but I do have a bit of a beer belly, the rest of me is pretty lean and muscular. I measured my chest at 44" while wearing a light hoodie. The size chart said I should be a large and so that's what I ordered. It fits perfectly, I can honestly say an XL would probably be too big. The large is not too tight, not too loose. I have plenty of room in my shoulders, and I can wear a flannel shirt and hoodie under it and button it closed comfortably. The arms are the perfect length for me as well, falling just past the wrist. I read a few reviews about the quality of the denim, I got the rinse color (dark wash) and it feels plenty high quality to me. No issues that I can see with the pockets, buttons, or stitching anywhere. I did however get a blank red tag on the front pocket which concerned me, I looked that up and apparently Levi manufacturers 10% of their products with blank red tags instead of saying "Levi" and supposedly that makes them more valuable because of the rarity? Whatever, I don't care about that as long as it's not a knockoff. I plan to wear this for a long time so the resell value is of little importance to me anyways. Even if it was a knockoff, I'd probably keep it anyways because of how good it looks. Overall I'm pretty happy with this purchase and would recommend.

“This Jacket Changed My Life, My Posture, and Possibly My Destiny.”
Special Size Type: Standard, Size: X-Large, Color: Colusa/Stretch
“This Jacket Changed My Life, My Posture, and Possibly My Destiny.” I bought this Levi’s Men’s Trucker Jacket on Black Friday for 50% off, and honestly, I think the universe has been waiting for this moment. The second I slipped it on, I felt the air shift — like somewhere, a tumbleweed rolled across a Walmart parking lot in respect. This jacket didn’t just fit. It claimed me. Suddenly, I walked differently. Not better — just with more narrative significance. Like I was the mysterious side character in a Netflix show who only appears to give life-changing advice next to a jukebox. People look at me now like I’ve been to places. Seen things. Done questionable but noble acts on the open road. What This Jacket Made Me Believe About Myself: That I could fix a motorcycle using only pliers and emotional willpower That I should own sunglasses even indoors That I absolutely should lean against things while staring into the distance That I have opinions about blues music That someone, somewhere, owes me money My confidence skyrocketed. My responsibilities? Stayed exactly the same — but I now ignore them with swagger. The Black Friday Factor Getting it 50% off activated a new primal ego inside me. Every time someone compliments it, I immediately shout: “THANKS — GOT IT HALF OFF!” Even when they weren’t complimenting it. Even when they weren’t talking to me. Even when I was alone. Durability This thing could survive: A bar fight A mild tornado Being run over by a shopping cart stampede The emotional collapse of a man who just realized he peaked in high school It’s rugged. It’s iconic. It smells faintly of “I could do better, but I won’t.” Side Effects (documented): Strangers nod at me Kids think I know how to play guitar I feel obligated to say things like “Let’s ride” even when entering a minivan My reflection winked at me once Final Verdict This isn’t just a jacket. It’s a lifestyle upgrade. A fabric-based personality transplant. A denim prophecy fulfilled. Five stars. If Levi’s ever discontinues this jacket, I will chain myself to their headquarters and demand justice.

Vintage 60's cool, but sizing is a difficult decision
I can't believe I haven't owned one of these for the last 40 years or so. To put one on after all these years takes one right back to the questionable days of one's youth when you wore these bare chested underneath while tooling around on your Kawasaki 500 triple. Well it will take you back if you haven't let yourself go too far! I received both a large and a medium in black (love the free returns on clothing, I always order two sizes so I get the right fit). They are both made in Mexico and look very neat and well made, the denim is on the thin side but OK for warm weather. Nowhere is there any tag saying shrink to fit or shrinks two sizes. The tag says machine wash cold, tumble dry medium. The large is quite large on me (I'm 5'9" 168 lbs trim and athletic build, more often than not I wear large in T shirts and jackets), the sleeves are way too long and loose, body too long and loose. Would have to shrink drastically to fit me, I really doubt it would shrink anywhere near that much. This type jacket is just all wrong if it's too loose fitting, witness the BLACK color one in the model photos, just not too cool. The medium fits much much smaller but IMHO perfect for this style jacket, a classic fit like Steve McQueen or Robert Plant would have sported, high waist and tight shoulders with sleeves rolled back a little. If you look at the model in the 'HARRINGTON' color you have the idea. It will be totally bitchen on today's big black BMW oilhead. This is the youthful fit I was looking for but any shrinkage would be too much. I am conflicted because I would like to wash this jacket and break it in, put a little wear and tear on it. But I wouldn't dare dry it with heat. I might try washing it in cold water and then line dry or I may just dry clean it. I am tempted to go out and drag it up and down the gravel driveway and run it over with my truck a few times till it acquires some of the same attitude it inspires in me. All I need now is a Psychedelic soundtrack and I'm all set to relive the glory days, better than the first time around. A little research on the Levi's website reveals they have a regular fit and a slim fit in addition to this relaxed fit which is the only one available on Amazon. I find that this relaxed version works well in the medium size anyway, it seems to be relaxed only in the body, not so much in shoulders or sleeves.

Large fits well, comfortable, though a bit more flex to it than expected
Special Size Type: Standard, Size: Large, Color: Colusa/Stretch
Very nice, though it is stretchier than expected. I purchased a large. The fit is good for me at 5'11" / 200lb, average build. My shoulders are a bit broader than most and the fit is maybe just a weeeeee bit tight, under the arm when reaching for something. The arm length and overall length are both great. This will be a mid-season jacket so I do not plan to wear a hoody or other bulky item under it. It would work, but I think a bit too snug for me. I reccomend washing it immeidately then taking a hot iron with steam to the pockets and collar which I feared were trying to start and curl up. They need to be trained early! I am more pleased than expected.
