Here's what I took into consideration: when the white LEDs age they shift towards blue. As MH and T5s age they shift towards red. So while an aging LED may in time shift color it's towards a color already in use in reefkeeping and not encouraging nuisance stuff like cyano, etc.Originally Posted by alton
So the worry is less about spectrum shift and more about intensity.
They have been around long enough to make me feel pretty confident that the quality LEDs in quality fixtures that are run at 100% for 5 years really do have a drop down to 70% is correct info.
Because I am such a planner I actually have it set to where even now I don't have it on 100%. I have white at 70% and blues at 40% each and I get a reminder email every 6 months to tweak it up 3% so when it is at the 5 year mark there's a good chance I can tweak out an extra year, maybe more because obviously I never run them at 100% and I definitely don't run them 24 hours at 100%.
Try tweaking your MHs or T5s up a few percent in a few months...
The only problem I see is really PRICE. it's expensive. But I love it. No regrets. The 4 modules on my 6ft tank are perfectly adequate for my reef even at 70%
