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.

Great for Slowing Down Snack Time
Size: Large (Pack of 1), Product Packaging: Standard Packaging
My dog, an English Lab, is a voracious chewer, and destroys most toys in a matter of seconds. He also swallows most snacks without even chewing, and finishes meals in record time. It takes him about 20 minutes to get everything out of the Kong, and since I hide it somewhere on our property, he also takes several minutes to find it. He seems to really love the challenge, and it’s nice to have him take more time with a snack. I tried the Kong Easy Treat to seal the toy, but I find peanut butter works just as well (especially when frozen after being filled and sealed), and it’s cheaper and easier to use.

This product actually lives up to the title of indestructible.
Size: Large (Pack of 1), Product Packaging: Standard Packaging, Size: Large (Pack of 1), Product Packaging: Standard Packaging
This is the only toy I've had which my dog hasn't destroyed in minutes. I have had a few others that will at least last a few months, but Kong extreme has held up over the years. I like the fact that I can stuff it with treats, bits of other "indestructible" toys and seal it up with peanut butter, then pop it in the freezer to give her an extra 15 minute challenge. I have a couple so I can clean one while she's busy with the other. This size seems to be the best for a ~90lb. dog, the large end being roughly the same size as a tennis ball, which she loves as well.

Great product but choose a size or two up
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Nice quality toy for long lasting and engaging play! One star docked for the sizing—I don't usually expect to need an xl anything for my 45lb border collie but he cant even fit his canine teeth into the large size to ease the jerky reward out in "hard" position but "easy" position he doesn't even tough the toy just grabs the jerky. Got an XL and it has been great for the jerky both easy and hard positioning. The larges I keep around for liquidy and frozen treats to keep the mess contained and they work very well for that.

Truly for Aggressive Chewers
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Excellent product for aggressive chewers. The black Kong doesn't last forever BUT it is the most reliable toy I've used with my 60# pitt mix. I've returned so many toys that were advertised as for this girl's level of enthusiasm that I no longer buy anything else.
