SANSI 36W Grow Light Bulb Review
The SANSI 36W is a high-output BR30 grow bulb with published PPF and PPFD figures. Here is what the listing says, how it compares, and who should skip it.
By Ethan Cole
Updated November 2, 2026
The SANSI 36W is a screw-in BR30 grow bulb that turns a floor or clamp lamp into a strong grow light. It is one of the few grow bulbs that publishes both PPF and PPFD, and at 36W it puts out far more than the 9W to 12W grow bulbs most people start with.
Safety note: grow lights are plug-in electrical fixtures. Follow each maker’s minimum distance from leaves, keep drivers, timers, and plugs away from watering and misting unless the listing gives a water rating, and do not look straight into the LEDs at close range. Lights with UV or IR diodes are marked in the specs below. We describe what each maker lists; we do not promise growth results for any plant.
Our Verdict
The SANSI 36W is the screw-in grow bulb to buy when a plant needs strong light and you already have a suitable lamp. It is rated 4.5 stars on about 2,600 Amazon ratings at the time of review (November 1, 2026) and is our top pick in the SANSI grow lights guide and the high-output pick in best grow light bulbs.
If your plant is a low-light type, or your lamp is rated below 36W, a 9W to 15W grow bulb is the better choice.

Output
SANSI publishes 65.6 umol/s of PPF, about four times the 16 umol/s GE lists for its 9W BR30 grow bulb. The PPFD figure of 265.58 at 1 foot tells you how much reaches a leaf at that distance; it drops as you move the bulb away. SANSI uses a secondary lens to direct the light.
Build and Safety
SANSI solders the LEDs onto a ceramic heat sink rather than an aluminum board and says this lowers thermal resistance. The body is rated V0 flame retardant and WF2 anti-corrosion, and the bulb is ETL listed. SANSI also notes low infrared output, so less heat radiates toward leaves.
Check that your lamp and socket are rated for at least 36W, and that the shade leaves room for a BR30, which is wider than a standard A19 bulb.

How It Compares
Against the GE Grow BR30, the SANSI uses four times the power and lists about four times the PPF; the GE suits low-light houseplants and has many more ratings. SANSI’s own 40W remote bulb adds dimming and a timer; its 32W bulb lists higher PPFD at 1 foot (423) with a narrower spread. See BR30 vs PAR38 for shape differences.
Who Should Buy It
Owners of succulents, citrus, or large houseplants who want strong light from a floor lamp or clamp lamp.
Who Should Look Elsewhere
Anyone lighting a whole shelf (use a panel), anyone who wants a built-in timer, or anyone with a small table lamp rated for 25W or less.
