View attachment 1043129Just freshened up my t 5's today , absolutely one of my favorites , keeps seedlings , clones , and small bushes super happy ....
I almost can't believe it myself , but I think this is the first light replacement in over 7 years ....
And the ones I swapped out still looked fine ......
The tubes are spec for 4 year lifespan with a 50% fail rate after 2 and about 20% lumen loss in 4 years. Goes down in a strady curve from about 6 mos.
Just fyi for average t-5 ho tubes.
