DISTANCE GUIDE (10W BULB)

Distance matters most if this grow light is your plant’s only light source.
Always start further away and adjust closer or further depending on plant response.

Seedlings, cuttings, young foliage: 75cm – 1m
Established plants / higher-light needs: 45cm – 75cm

Move the light closer if growth is slow or leggy.
Move it further away if leaves look stressed or washed out.

WHICH WATTAGE SHOULD YOU CHOOSE?

36W — For large collections or very bright-light plants
Best for wide coverage, higher mounting, greenhouses, large grow tents, succulents, cacti, and small fruiting plants.
Higher intensity allows mounting further away.

24W — The most popular all-rounder
Ideal for medium-sized indoor plant collections or using two lights to avoid directional growth.
A great balance of intensity and coverage.

15W — For small collections & propagation
Perfect for propagation tanks, trays of seedlings, plant shelves, small grow tents, and compact plant setups like African Violets.

10W — For small setups or close mounting
Best when the light needs to be mounted close to plants — single trays, shelves, or a small number of plants.
The smallest and least conspicuous option, fitting the widest range of lamps and shades.

WHAT TO PUT YOUR GROW LIGHT IN

Sansi bulbs use a standard NZ E27 screw-in fitting, making them compatible with most:

• Desk lamps
• Floor lamps
• Pendant cord kits

Grow light bulbs are wider and longer than standard bulbs, but the 10W is similar in size to a standard round bulb and fits easily into most lamps. Shades aren’t required, but if used, allow at least 3cm of airflow around the bulb to prevent overheating.

The 10W and 15W bulbs generally fit comfortably into most lamps with shades, while the 24W and 36W bulbs are larger and may require more open fixtures.
