How far away from my plants should this grow light be?

 

How to use a distance guide

Distance matters more if this will be your plants only light source (which is what the following distances are based on). Keep in mind different plants have different light requirements, so start at the higher / further away of the distance range and adjust closer or further away depending on the plants light requirements. Closer if growth is slow or leggy, further away if leaves look to be getting too much light.

Distance guide (36 watt)

1 metre to 1.5 metres away for seedlings and cuttings (coverage 27 square feet / 2.5 square metres)

75cms to 1 metre distance for foliage growth (coverage 12 square feet / 1.1 square metres)

45cm to 75cms for blooming and fruit production (coverage of 3 square feet or 0.3 square metres)


10, 15, 24 watt or 36 watt?



36 WATT For a bigger collection, to cover a larger area, to mount higher up / further away for wider coverage, for a small greenhouse, for a large grow tent, or for a collection of plants that prefer very bright or direct light (including succulents and cacti), go for the 36 watt. Also for small trees and fruit production for larger, established plants. Coverage area is larger and output more intense, so it can also go higher up / further away than lower wattage bulbs. The extra bank of lights in the centre compared to the 24 watt offers higher light intensity for up to small greenhouses or larger grow tents.


24 WATT For a medium-size indoor plant collection or if you want two lights (which avoids plants growing towards one direction only), choose one or two of the 24 watt. Watch the video below which shows the 24 watt. One or two 24 watts are the most popular choice for most indoor plant hobbyists (you can always start with one and get a second later). 


15 WATT For smaller collections, for using over a prop tank, for a tray of seedlings or cuttings, for lighting up individual plant shelves, for use inside small grow tents and for baby plants and smaller-growing plants like African Violets, one or two of the 15 watt or 10 watt are ideal, with the 15 watt being the more popular of the two.


10 WATT The 10 watt is the better choice when you need to mount the light closer to plants (such as over the top to cover one tray of seedlings or to light up one plant shelf), or for a smaller number of plants. The 10 watt also fits the biggest range of lamps. It has the same standard E27 screw-in fitting as all sizes, but is not as wide or long as the 15 watt, so less conspicuous if you want a more aesthetic solution than can be hidden within most shades. 


What to put your grow light in



Since Sansi have a standard NZ E27 screw-in fitting, you'll find they are compatible with most desk lamps, floor lamps and pendant cord kits. However, grow lights have wider and longer bulbs than standard indoor lightbulbs so if you want a shade, look for one that's longer / wider than standard. As Sansi grow lights are directional, a shade isn't required (see the video below showing the beam without a shade).


Although LED grow lights run cooler so don't have the same risk of burning your plants, they still need some airflow around the bulb, so I'd allow a good 3cms or so extra on all sides, meaning you may need either no shade (recommended), or a wider than usual shade in an area with good airflow so things don't get too hot which risks burning out your bulb.


Have a watch of the video below for an idea of size as the 24 watt (in the video) and 36 watt are a similar larger size whereas the 15 watt and 10 watt are small enough to fit with plenty of room around them in most lamps with shades. The 10 watt is a similar size to a standard round light bulb.


I suggest buying your bulb before your lamp and taking your bulb shopping with you to check fit in-store - or just purchase your lamp from a store who is relaxed about change of mind returns if you find it doesn't fit - and keep your receipt!


If you prefer to hang it either from the ceiling or from an L bracket on the wall, I also have these pendant cord kits available in 4 colours that have E27 fittings and are rated for up to 60 watt bulbs so are compatible with the Sansi bulbs.


To get a better idea of the bulb size, brightness and distance from plants, have a watch of this video which uses the 24 watt size:


 

Included: Bulb in box as shown. Pendant cords or other accessories shown are not included (available separately). 


Warranty: Sansi says their LEDs are rated to run for up to 50,000 hours in theory, BUT that doesn't account for conditions in our homes. Factors like heat, moisture, airflow and more can have a big impact on how long a bulb will last.

As you can tell from the price, Sansi are great value-for-money for an entry-level solution to boost light levels for houseplants grown indoors, but are not a high-end, premium solution. 

In my own use at home I find I get 1 to 3 years per Sansi bulb and at that stage they usually still work, but slowly become dimmer over time (called lumen degradation, normal for all LEDs). 

I provide a 6 month warranty on electrical items I sell (including Sansi bulbs), which covers manufacturing faults and defects. It doesn't cover wear and tear, accidents or faults caused by conditions. The consumer guarantees act also applies to home use.

IMMEDIATE REACTION, PLUS FOLLOW UP AFTER A WEEK!
Style: For Him
**Package arrived LITERALLY 5 minutes ago, here is my immediate initial reaction, and then I'll actually post this after USING the soap and getting a better feel for the product.** Keeping in mind that smell is subjective, here are my knee jerk thoughts on the bars of soap: - Firstly, I can smell the soap through the bag (and box). Whatever scent this is, it's POTENT. - Opening the box, the bars of soap look a LITTLE small. Not egregiously so, but a little bit smaller than your average bar of soap; BUT I check them against a new bar of Dove soap that I have, and they are identical. The eyes are playing tricks on you with these. - Here is the breakdown of the 6 scents - Activated Charcoal. This is what I was HOPING would smell like the "Pine Tar" that other companies (like Dr. Squatch, which I've never used, btw) have, but it is the "soap-est" smelling soap, with a hint of tar. It smells a little bit like a can of new paint. - Tango Mango. IMHO, the best smelling of the 6, with strong citrus smells. Very lemon-y, but pleasant. - Eucamint. Ahhh, here's what was permiating out of the box. This smell is STRONG, with an AGGRESSIVE mint smell. Like, Ben Gay mint. And as strong to boot. It doesn't smell BAD, but it's hands down the strongest scent. - Oatmeal Shea. Meh. Kinda smells like an old coat that would be hanging in your grandfathers closet. It's not a BAD smell, but it has this weird odor to it, like when you leave a can of peanuts in your cupboard for a long time, and then go back and smell it. - Patchouli Lime. This one kind of smells like a mixture of Activated Charcoal, Eucamint and Oatmeal Shea. It smells like a room that you just painted a day or two ago, and it definitely has the Ben Gay after aroma lingering. - Apline Spice. This smells like a box. Like find an empty cardboard box, open it, and take a whiff. Boom, Alpine Spice. My least favorite. I will say, none of them STINK; as in there isn't a smell that I'm like, "ewww, I don't want to smell like AT ALL!" Which sounds weird, because I described some of them as "paint," "an old coat," and "a cardboard box," but I feel that those are just very passive smells, not aggressively bad ones. If there is a problem soap, I would assume it's going to be Eucamint, because it might just be too overpowering, although I've found that the more you smell them, they seem to mellow out. I imagine that after a shower with these, the smell will dissipate enough that it will be more mild. Still, with the exception of Tango Mango; a very good smelling soap mind you, I'd say they are all very "manly" scents, and I'm excited to try them out. Ok, so I'm a little over a week in, and here's my final take. (I made it through Activated Charcoal and Tango Mango): First, the scents ABSOLUTELY mellow out when used to actually shower with them. My wife, who admittedly isn't really up on me like that, hasn't even mentioned me smelling differently than the last 11 years. So, if she's even noticed, it's not on a level to make a fuss about. This is important because fresh from the box, these things have some powerful scents, but they are definitely tamed by washing with them. The bars last ABOUT 7 showers. Obviously, your mileage will vary based on how long you're in the shower, how much you scrub, how you store them, etc, but I was able to get 7 GOOD showers out of these. I have them in these natural sisal (whatever that is) exfoliating bags that help lather and store the soap, and really did some good scrubbing in my showers. The bars lather decently, but I'm not sure how much the bag helps with that. If you are a once a day showerer, a bar a week is a very fair approximation of what you'll get. I definitely felt.....SOMETHING I didn't before with my shower gel showers. I don't know if that's the moisturizing, or the exfoliation, but my skin felt a little different after showering. A decent buy. I'm not thrilled, but I'm not upset either. I don't think it changed my life, or even the way I shower, but I'm not mad at the experiment. I may try the Dr. Squatch soaps to see how all these stack up.

Convinced to make the switch
Style: Citrus
Love this soap. I was using Jukebox, but I'm making the switch. Crate 61 feels better on my skin, the bars last a little longer and the 6 pack is $15 cheaper than I was paying for 6 bars with the Jukebox subscription. I get extremely dirty at my job so I tend to go through soap faster than the average women. Jukebox bars would last me about 4 days. These will last 6 or 7 days. Jukebox bars were a definite upgrade from body wash, but it would irritate the sensitive areas. I don't have that issue with this soap. Jukebox bars smell nice in the shower, but I feel like the scent didn't last beyond that. Crate 61 leaves a pleasantly subtle smell on my skin after showering. The only benefit with Jukebox is that you can choose the individual soaps in your 6 pack, rather than selecting one of the collections.

Natural, Gentle, and Smells Great
Style: Most Popular
I picked these up to try something more natural, and I love them. They lather well, feel gentle on the skin, and leave it feeling clean without drying it out. The scents are really nice too. They feel like good quality bars.

Longevity, scent, quality 10/10
Style: Most Popular
I’ve gone through just about the whole box and I will be buying more. I bought these early November 2025 and now that it’s almost May of 2026 I’m down to my last two bars so id say they last awhile. I use them for body wash and will be using them for hand soap once I go through my stash of bar soaps from other brands. It lathers nicely, with a light scent, natural not over bearing chemical scents. I use this as body wash and hand soap. I haven’t noticed any skin irritation, just a good ole natural soap (: I love how there’s no plastic in sight other than maybe amazon packaging

Better than expected...
Style: For Him
I love going to a craft show or a place that sells a handcrafted soap. A good craftsperson can produce a high-quality soap that cleanses, moisturizes, and leaves a good scent. I gave these a shot after running out of those soaps. They did beat my expectations. I thought these would be a factory produced and chemically. While you can tell these are churned out pretty regularly in some sort of factory, the overall quality is good. Each scent is full and unique without being overpowering. They seem to be natural and not generic chemical smells. Really enjoy each of the unique scents. The bars themselves aren't that big. They come in a piece of cardboard and are very uniform. There is some texture to the soap, as well as an added bit of something to give it some grit. I like it. This isn't lava soap but there is something (about the size of fresh ground pepped) mixed throughout each bar. A drawback overall is how long they last. I would estimate less than a week for a daily user. I thought, given the denseness, they would last for a longer than they do. I'll probably use the entire box in under a month. Of note is the lack of slimy or slipperiness to the soap. I like this. Some soaps that I've used in the past leave you slimy and you can barely hang on to the bar. This rinses very well and doesn't make you feel slimy. Overall, these are a good replacement for the 'true' homemade soap. I am happy with them and would purchase them again.
