What is the longevity of components on these PLL's ?I would imagine the workhorse ballasts last ok? Is bulb failure an issue?
IM STILL USING 4 X 54W pll
PLL = phase locked loop, sometimes.
what does it mean with LED lights ?
Some years ago I had a par meter passing through my house and measured my pll and diy led sets. Led had double the par for half the wattage if I remember correctly. I put all my pll fixtures in a box, for future use. I do use cfl for UV a/b, as there are no good affordable leds for this. Yet.I stopped using the pll at 10,000K. Went over to LED replacement for pll at 6400K . I am using LED at around 4000K now and the other area at 5000K because I can get more lumens out of these lights. Easier to just use LED but I wish they went higher in Kelvin.
Not sure what I gave up in quality using LED, if anything. I would have to run a side by side using clones.
