Dude, tinyurl.com

I use them till they die.

Looks like the sensible thing to do. Unless there is more to aquarium
lights than lumens. Is there?

Nope.

Prove it to yourself. Try a pair of really old high CRI full spectrum 10K tubes
then try a pair of new cool/warm whites and observe the difference.

In other words, yes Virginia, new $7 tubes work better than old $40 tubes.
