Customer Questions & Answers

will these bulbs work in standard fixture

standard 2 bulb Fluorescent fixture
Asked by: jesse
They are thinner than an ordinary household fixture and will not fit in that kind of fixture. They are designed to fit into a specific grow- light fixture. You can research online and find what color bulb for a standard fixture will work for growing plants. We used to do that when we lived where we could supplement with sunlight.

how much does it cost to run this fixture?

Asked by: Bri
This fixture has four 54 watts bulbs for a total of 216 watts. Depending on how much your electricity provider charges you per kilo watt hour determines how much you will be charged for that 216 watts. As an example this is similar to running almost four 60 watt kitchen can lights. Hope this helps for further information. Thank you

Rated 4 out of 5 by from These are good T5 HO replacement tubes T5 HO tubes at 6500 Kelvin burn at the blue (bright daylight) end of the spectrum. Great for initial growth and getting started. They put out a lot of light (up to 5,000 lumens) for the electricity used (it is lumens, not watts that the plants respond to). Yes, they are smaller than reg fluorescent tubes and require their own fixture. DUH! They give off very little heat and can be placed within an inch or so of the canopy without heat burn. 3000 Kelvin tubes are at the warm end of the spectrum and are better for wrapping up/blooming stage. A mix of both works well once the plant has established a good root system, sturdy stalks/stems, and are ready to flower. Begin with 6500K, then switch to a mix of 3 & 6.5 Kelvins, then when the plant is winding down, switch to all 3000 Kelvins. That mimics the beginning of summer, middle of summer, and the approach of fall (to the plant). These bulbs are average grade and good enough. There is a lumen drop over time but at this price you can exchange them twice as often, keeping your plants receiving closer to the 5K lumens per tube they start out at. Pretty darn good. The other reviewer's issue was not with the tube, it was with the FO (faulty operator). I grow very rare orchids in a lab and have learned over time T5 HO is more than sufficient to get a great job done. These tubes are cost effective (IMHO) and do the job.

Rated 5 out of 5 by from very good light i bought 2 of these lights for my shop along with other kind of lights i had in there . wow what a difference . really light thing up . i think they are not cheap by no means ' but usually you get what you pay for . but at 11 dollars a bulb you better not drop any . 2 things i didn't like . one the directions could have been better as to how to wire the lights . and to i had to order the bulbs seperate as the store didn't have the 54 watt bulbs in stock that i could use for the lights but i ordered them through the store and they were delivered to my house 'only thing i had to wait a few days. total about $193. . 8 bulbs ans 2 fixtures . but it is great to be able to see .

Rated 5 out of 5 by from Great light for the value - and growing plants I had issues getting the lights to withstand shipping when I ordered them elsewhere. I was very impressed with the sturdiness of the packaging. All my lights made it without issue or damage.
