5.0 out of 5 stars Does what it supposed to to, grow plant!
Reviewed in Canada on 26 October 2019
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.

1.0 out of 5 stars Dim Wits.
Reviewed in Canada on 1 March 2018
Packaged arrived. Fit into the slots perfectly. But where they all failed and caused me to never want to buy another is, it’s no brighter than the burnt buld I just took out. Incredible dim. Complete waste of money, time and energy. Go to your local growstore or home depot before you get robbed.
