Get your grow on even in winter. Light up those dark corners and low-light areas. Sansi LED grow lights produce full-spectrum, white light that mimics the way our eyes see sunlight, but without the burning UV rays. This is for the 15 watt bulb.

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 higher / further away 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 (15 watt)

75cms to 1.5 metres distance for seedlings, cuttings and foliage growth when small.

45cms to 75cms for higher-light requirements and once plants are established. 

10, 15, 24 watt or 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 plants that prefer very bright or direct light (including succulents and cacti), go for the 36 watt.

The 36 watt is also better for small trees and for fruit production for larger, established plants. The coverage area is larger and output more intense, so it can also go higher up than the lower wattage bulbs. As it has an extra bank of lights in the centre compared to the 24 watt, offering higher light intensity, for up to small greenhouses or larger grow tents.

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). 

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.

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 so you can take your bulb shopping with you to check the fit in-store - or to 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:
