Active Grow 22W T8 HO 4FT Horticultural Lamp

Overview 

The Active Grow 22W T8 High-Output Horticultural Lamp is an LED tube that replaces 32W/40W T8/T12 fluorescent lamps and features 30% higher PPF output, lower power consumption and 100% more effective spectrums for plant growth. The T8 LED Horticultural Lamp has a 190° beam angle for wide light distribution and runs cool, so it can be placed closer to plants and save space. Each lamp is protected by ClearSync film technology that improves water-resistance and prevents glass shattering without sacrificing photon output. All Active Grow T8 LED tubes work with existing T8 or T12 fluorescent light fixtures by bypassing the ballast and wiring to single-ended power on universal 120-277 voltage. Without the need for a ballast these lamps do not flicker, buzz or experience longevity issues. T8 fixtures require non-shunted lamp holders (tombstones) and are non-dimmable.

T8/T12 LED GROW LIGHT BALLAST BYPASS INSTRUCTIONS

Fluorescent Fixture Retrofit Instructions

Watch the video to learn the steps it takes to bypass a standard T8/T12 fixture’s ballast by wiring directly to single-ended 120-277 volt circuits. Bypassing the ballast helps not only lower wattage, amperage and heat output but avoids flickering, buzzing, longevity issues and other problems associated with ballasts.

A total game changer (where were these when I was a teen?!)
Size: 72 Count (Pack of 1)
I honestly wish these had been around when I was younger! The Mighty Patch Original is hands-down the most effective way I’ve found to deal with stubborn whiteheads. Instead of picking at my skin and making things worse, I just pop one of these on at night and let it do the work while I sleep. By the morning, you can actually see the gunk it pulled out right on the patch (gross, but strangely satisfying). It significantly reduces the size and redness of the zit in just one use, and because it covers the spot, it stops me from touching it and causing more irritation. The 72-count pack is a great value and lasts quite a while. They stay put all night, even if you toss and turn, and they’re clear enough that you almost forget you’re wearing them. If you’re looking for a stress-free way to clear up your skin overnight, these are a must-have!

Works on all skin types
Size: 36 Count (Pack of 1)
What an amazing product! I'm in my 40s and still experience occasional acne. I purchased Mighty Patch, and after wearing it overnight, my blemish was noticeably cleared up by morning. I have fairly dry skin and already use quality skincare products both morning and night, so I was impressed by how well it worked. My 17-year-old son also tried one when he started getting a few breakouts, and it cleared up his blemish as well. His skin is much oilier than mine, which shows that this product can be effective for both dry and oily skin types. I’m very happy with the results and will definitely be purchasing it again!

Doesn't replace good hygiene efforts
Size: 36 Count (Pack of 1)
It's not a miracle patch if that's what people are buying it for. The patch, once skin has been cleansed and dried, adheres well and stays put overnight. The patch does pull out dead white cells but never has it been one patch and done. I am finding that another patch has to go on to the blemish as it's now open and very red. So depending on how big the blemish is, determins how many patches you will need to fully clear up. On a great note: It does help with preveting me from touching it or picking at it which does indeed help the blemish heal faster. I keep a box in my medicine cabinet for really big, very noticable , blemishes, but I don't find it very cost effective nor do I find that my blemishes are cleared up 100% with use. It's really more a matter of: stop touching your face with dirty hands, don't go to bed with makeup on, stop squeezing/popping white heads, invest in a good facial cleanser with proven ingredients. There is no miracle patch. It's an good product for sure, but not a miracle. It will not replace good hygeine and a good cleanser.
