SANSI 250W Equivalent LED Grow Light Bulb, BR30 24W 3000K 5000K Red 660nm Infrared 730nm Full Spectrum Grow Bulb, IP54 Waterproof Grow Light for Indoor Outdoor Plants

The light has no visible flicker if you are sensitive to that. The driver is a quality constant current model and is even conformal coated - enhancing the water resistance factor. The LED chips are mounted to a ceramic disc which in turn is attached to an aluminum disc that is press fit against the outside casing - also aluminum. This cools the LEDs reasonably well but the driver is left uncooled which is unfortunately common. I decided to remedy this and was able to disassemble the bulb by prying the plastic lens cover off and then prying the aluminum disc out. The driver was then exposed though it could not be removed without desoldering the 120v leads. I replaced the driver's RS1 2 ohm sense resistor with a 2.2 ohm, dropping the wattage down to ~18 watts. It runs very cool now and should last longer.

Thus works exactly as expected as a grow light. My plants love it and they can't get enough!! The base gets warm/hot, not searing, you can the bulb off in a pinch from the head.

I bought this light to supplement natural light for my potted citrus trees in the winter. They go outside once it warms up in the spring but they get so sad in the winter. I bought a basic lamp fixture from the Color Cord Company plus a timer so it comes on and goes off automatically. It's working great and I don't feel any heat coming from the lamp. I will experiment with lowering or raising it once I see how the plants are responding to it. I have more citrus trees arriving in the spring so I might add a second light to extend the canopy. Overall, super happy with this light!

These bulbs are bright!! Haven't had them long enough to evaluate the results for growing. Great product and so far they have been on long hours without a problem.

Used it for a bird of paradise. I bought two the same size, but the one under this light grew 12 inches more than the one under a halo grow light.

Bought as Christmas present. It is nice and bright, but unfortunately the first unit began rapidly flashing off/on after several hours of operation (less than a day). Exchanged through Amazon for a replacement. Second unit began exact same flashing issue, but after about only 30 minutes of operation. Have now returned for a refund. Did swap to a different socket, but same thing happened. The bulb is suspended in free air in a room that is about 68F. It should also be noted that the first unit had a date code in 2024 and the second had a date code in 2025. Given all the good reviews, I am perplexed by getting 2 units with the exact same issue but from different lot date codes. This might just be simple coincidence, but it also may be related a design and/or manufacturing issue to be avoided.

Pros: Bright - The bulb is approximately 12,000 Lux at 12 inches measured using a PARwise Smart Submersible Quantum (PAR) Sensor (see spectrum graph) Color - The bulb has a pleasant warmer soft white. It appears to render colors of objects slightly warmer compared to natural sunlight. Noise - The bulb is completely silent, with no audible buzzing or vibrations. Build quality - The bulb feels sturdy with a robust heat sink and appears waterproof as advertised. Warranty - The bulb comes with a 5-year warranty, which under normal use, should exceed expectations for the lifespan. Neutral Heat - The light bulb measured approximately 135* F when measured with my Pixel 8 Pro's built in thermometer. Lifespan - I cannot speak on the lifespan, as I've only had the bulb for a few days. However, I believe 135* bulb temperature is low for and LED, so lifespan should not be an issue. Cons: The bulb flickers when my neighbor's HVAC unit cycles on and off. I have also experienced random flicker lasting a few seconds (see video). This bulb does not include a remote or timer but is easily remedied with a smart plug. Dimming capability would be beneficial, which may also prevent bulb flickering.

It was not powerful enough for my tropical plants. I had to get a different light from sansi. This was my first time buying one so i had not learned yet. Always look at what the ppfd(the amount photons(light) that is landing on the plant) is for how far away you have your plants from the light. Sansi is great because they show the ppfd at 1ft 2ft distance. I have tropical plants so they need much higher ppfd then some house plants. But I love this company and all my lights are by them. This just wasn't the right bulb for my situation.
