you hold them like a flashlight
I won't lie. The build quality is ABSOLUTELY AWFUL on these. The plastic is flimsy, the aluminum extrusions are PAPER thin. I dropped one on my foot/shoe (at the distance from my hip) , and it crinkled the aluminum. That being said... You mount them on your ceiling and never touch them again. You don't move lights around... you hold them like a flashlight. You put some screws in the ceiling, run the wiring... plug them in. And never touch them again. So I don't care that they are made flimsy. Like everyone else says. The light is bright as could be. Its right down the middle of Warm light and Cool blue. For the price, I highly recommend them. Just be prepared to buy some wiring extensions, unless you run them back to back.
Great for growing seedlings
Put the 6 of these to cover a 6X2 growing area for seedlings. These bulbs are super bright and true daylight color. Most research I read say that plants will not flower under 6500K daylight only, but my beans and cucumbers both did, as we had a longer than expected cold spring. The cucumbers even started into fruit. I intend to buy another couple sets, to expand my growing area for next spring and probably a couple sets for the garage.
Super bright, and easy to install. I put up 6 in my garage/shop, and have no more dark spots. Was pleasantly surprised to see these are a 2 pronged polarized plug. Since I as lazy and didn't want to tie into my wiring, this allowed me to use a light socket adapter to power the lights and turn them on/off using the light switch. We'll see how they last over the next few months, and how they hold up in winter. I'll update if there are any issues.
Can't live without them. No eye strain.
These lights are perfect! 6500k matches my computer monitor's frequency, which is awesome because I do graphic design and it doesn't mess up my colors or flicker. When I am done designing I also have 12 of these lights in my vehicle wrap installation bay. They are so perfectly bright that I can find defects in the paint on cars before I start the wrap installation. I can not live without these lights. My eye strain is zero when I have finished working under them for 12 hours straight. Oh and these lights are so light and they have a nice aluminum casing. They even work when it is 10 below 0. I have had them for more than 6 months of continuous work and they are not any dimmer since the day I installed them. l have 6 bulbs linked all on one switch, super easy to install. All you need is a Philips head screw driver and a ladder.
There are a lot of various parameters for lighting, such as lumen, PAR, CRI, spectrum and so on. And for grow lights, what should we care about? What is...
