100W Led Grow Light Bulb for Indoor Plants, Pure White Full Spectrum Grow Lights for Seed Starting, Growing, E26 Grow Lamp for Garden, Vegetables, Greenhouse, Hydroponic, Aquarium

This bulb is not even equal to a $5.00 LAMP LED i PURCHASED AT local store. Low bright ness .

Sounds like mark got a lemon , the product is not sharp or awkward at all, very durable , stays nice and cool, great light over all! Will be ordering more for my planted aquarium

It's a bit too heavy for my lamp to stay up.

First time ever in my life I am winterizing my citrus trees, we live in Dallas TX .I researched extensively what lighting to use. I found out that Kelvin number ("temperature" of led) equals to sun in different seasons and affects plants differently.Whiter light, cool white (4200 -6000 K) is like mid summer mid-day sun. It promotes foliage and is good for herbs.Warmer light, yellower, low K number (2000-4100) is like fall sun, it promotes flowering, fruiting, but can cause elongation of the stems. I wanted to avoid leggy branches, cause my trees barely fit this greenhouse already.So i chose these cool 5000 K lights with some of the UV and IR. The 20w that equals to 100 claimed is the strongest full spectrum I could find. So I ordered these.Despite cool lighting, one of my mini lime trees flowers like crazy with bunches of tiny limes here and there. The others are just doing ok. Definitely not worse.I use these lights with another brand lamps with slightly warmer temperature (4200), i hsve it all mixed up, but the trees under these lights are behaving well.So, I guess that's a 5 star rating from my plants.Lamp is bright, is on for 14-18 hrs a day, stays cool, no fan in it (and I don't need one too).I only wish they made a bigger wattage lamp with same characteristics (5000k broad band with UV and IR) . I would purchase.
