5 Pack Horticulture 2FT/22IN 6500K T5 Fluorescent Grow Light Bulbs

Exceptionally packed securely! Great value, awesome lights!! 100% buy from this Seller!

If I could give zero, I would- terrible !!! Bulbs blown and I only used them for 2 months- a waste of money. I have my old T5 Light bulbs from another vendor that are still going strong for over 5 years!!! I only used the grow lights to start seedlings for a short period of time. There is no reason these lights should fail so soon.

Just do yourself a favor and don't make price your biggest concern. These bulbs drop in brightness within the first 6 months and then they start burning out like crazy. I purchased a package of these in February and have used them 18 hours a day until January 2027 so about 10 months. The brightness had dropped by almost half at the 6-month mark as measured with a light meter. only one of them are still working In January 26th. They burn out prematurely as normal t5 fluorescents last several years out of the box. They sell a lot of them apparently because they show up at the top of the search results and they have a competitive price. Unfortunately they suck and I've been buying these type bulbs for over 20 years.

Decided to give this a try due to local prices just going up and up, nothing to lose I thought. Bought, it arrived quite quickly, threw them into my T5HO fixtures and watched the plants. In a few short days the plant responded to the new bulb and it 6500K spectrum. They are appropriately packaged within their own cardboard tube. Long story short, I'd recommend this to anyone looking for a T5HO grow bulb. Specs that I had measured...lux and PAR at 12", 24" and 36". lux - 12" ( 480 lux ), 24" ( 156 lux ), 36" ( 78 lux ) par - 12" ( 14.2 PAR ), 24" ( 7.0 PAR ), 36" ( 2.2 PAR ) My readings compared against manufactured specs equate fine and I'm happy with my results. wattage runs true at 20 watts per bulb My opinion on these T5HO tubes are that they are good for spectrum as they do grow plant well. To get the most out of the light, I'd suggest to have in the 6" - 12" distance range between light fixture and top of plant. Ideally a bank of 2 - 4 bulbs are best in any T5HO light setup so that each plant leaf is given the appropriate amount of light spread. Personally I use these in a bank of 4 bulbs to get the light spread at a distance of roughly 10" from plant top. An honest review

great packaging. light is bright. plants like it.
