Review: Work great - These are great. Work really well and whilst reviews I have seen say they buzz. I have not experienced this at all
Review: Great lights for early plantings SANSI 15W LED Grow Light Bulb 2 pack - I was looking for some lights for a reasonable price and low wattage to support early planting of seeds and came across the Sansi LED full spectrum grow light range. I ordered and received the 15W LED Grow light 2 pack end of January and started to use them on my early planting of tomatoes and other seedlings. Using a soil moisture & pH tester that has a light meter measuring LUX, I get 200 to 800 LUX in my beam of light which appear to be giving enough support for my new seedlings based on my rigged setup. (Outdoor cloudy day light gives a measure of 2000 LUX.) I rigged up a growing area using empty veg boxes that you can pick up from you supermarket, using clip on lights with a BC to E27 adaptor to then shine down onto the plants. I use a timer set for 12 hour a day to support their growth. See photo. I definitely think these lights have really helped in their progress and to avoid leggy seedlings and to support their growth between end of Jan 21 to early April 21 for this period I am writing this review. I've been able to germinate and grow tomatoes, aubergine (early long purple 3), herbs and a variety of different early flowers (Coleus, Salvia have done well with big leaves) with the help of these lights to give a good head start in the growing season. You definitely need more than 2 lights and space if you plan to expand what you are growing. In addition to above, I rigged shortly after 2 x18W strip lights to help support my additional growth which was not as convenient to setup. Those only give off 300 LUX so not as powerful and don't know if full spectrum. I recently ordered & received my 36W LED grow lights so looking forward to see how they will support my other houseplants. I've not been able to compare them with the 36W LED grow lights yet, but for the narrower beam, low wattage, price point, and good results, these 15W LED grow lights 2pack have been a good buy. And when Sansi has offers, these would be even better. The quick delivery from Sansi/desertcart has been good too.

## Features

- 4000K SUNLIKE FULL SPECTRUM: SANSI mixes 400-780nm all wavelengths in every LED chip and each SANSI plant light bulb is designed with an evenly distributed 60° beam angle and high-quality lens, which ensures a more uniform light distribution and avoids light loss, providing the best environment for your lovely indoor plants.
- SECONDARY OPTICAL DESIGN: The high light transmittance lens provides a secondary scientific light distribution, which can offer an average PPF of 27 umol/s and an average PPFD of 153 μmol/s/㎡@1FT and its 60° lighting angle gives plants more supplementary light and avoids light loss.
- TWO WEEKS MAKE A DIFFERENCE: SANSI LED grow light bulb could simulates sunlike light and emits no-harmful natural white light to help your indoor plants grow faster and healthier. Recommended coverage area up to about 4.20 sq. ft. mounted 18”-24” above the plants. Just 2 weeks to witness the miracle growth for your plants.
- COC PATENTED TECHNOLOGY: SANSI welds the led chips on the ceramic (COC: Chips on Ceramic) and adopts the features of the ceramic material (Insulation & flame retardant) and unique hollowed-out structure to fasten heat dissipation and thus prolongs the bulb’s lifetime to 25,000 hrs.
- CUSTOMER SERVICE & WARRANTY: Free-return within 30days without reasons and free to get a brand new replacement within 2 years for any quality-related issues. If you have any questions about our products, please feel free to contact us and we will give you a satisfied response within 24H.
- INSTALLATION AND SUGGESTION: Suitable for any standard E27 sockets. To ensure a longer and safer use, please DO NOT put our plant grow light bulb in an enclosed lamp fixture or with the lampshade because it will affect thier cooling effect and thus ends their service life in advance.

## Questions & Answers

**Q: rather than mains 240V, can i use the light with a battery connection? i.e. a 12V car battery**
A: In theory this is probably possible as the LED chips will not be mains voltage - BUT do yourself a favour and find a doable solution. If you really must use this lamp and you really must use a 12V battery then look for a low power inverter that might be used to power mains equipment in a camper van or other vehicle.

**Q: Anyone know what the 15 watts equivalent is?**
A: Around 150

**Q: Are these grow light bulbs flicker free ?**
A: Dear customer
Our plant lights will not flicker

**Q: is the newer type bulb better than the older version**
A: I have both the old and new bulbs and use them adjacent to each other. The new bulb is larger in size so looks a bit bulkier but that said because the surface which emits the led light is larger, the area where the light spreads seems larger. Also I think the light from the new bulb is whiter so seems brighter because of this. The old one was slightly more yellow and so a bit more subtle. In regards to the effect on the plants - my plants have loved both bulbs and they have been plant savers especially during the darkness of the winter days.

### ⭐⭐⭐⭐ Very bright
*by M***H on 1 December 2022*

Whilst I thought this was expensive it is very bright and my plants seem to be loving it. It’s quite heavy so needs a good fixture, mine is in a strong clip on fitting. Hopefully it’ll last a good while.
