Photo Light Bulb - Pack of 4 - CFL 45 watt - Daylight Balanced 6500K - Pure White Light, AGG871

Actually bought these as grow lights, and they work great for that. No duds, all 4 work. Light most high wattage CFLs they take a few seconds to reach full brightness, but these are faster than most. These also don't seem to heat up as much as my other high powered CFL bulbs, which implies they might be more efficient. Well packed in individual Styrofoam filled boxes - it would take a lot to damage these in shipping. Nothing to complain about here.

So far I have not noticed any difference between these bulbs and those costing a lot more. The intensity and color values all work well with both digital and film, and perfect with Zoom backgrounds.

Doing a great job for grow lights.

I wanted a florescent bulb that was similar to natural light for growing African violets, and so far it seems to be helping my plants.

I love the brightness and the length is still (just) manageable.

I can't believe I have to warn people about a $9 light bulb!!!! Literally, a bulb that does WORSE than a household bulb that comes in a FOUR PACK for the SAME cost that are identical in lumens and color. Three out of the four I bought FAILED. Two of them stopped working entirely, and the third now only lights up 1/3 of the way.I bought these only 2.25 months ago!!! I don't even use them every day!

I bought these lights to use in my cannabis grow room.I have used them for 3 separate grows.They provide great lumen output, which provided my plants with extra energy to produce beautiful trichomes.When combined with a 150 HPS Bulb and fixture, these CFLs allow additional light to penetrate buds under the canopy.

The bulbs are mostly functional and work pretty well. I only give 4 stars because despite most of the bulbs being great, one of the bulbs I received did not stay lit unless held at a particular angle. Other bulbs from the set worked perfectly in the same socket.
