I am not sure there IS a cheap lamp place that I would trust to actually sell what they claim to be selling.
While it has no crushing effect on the corals per se, it will encourage algal growth which no one wants.
So Foster and Smith are telling you about the "lifetime' of the lamp, you want to stay focused on the actual
spectral-accuracy life of the lamp. Which is about half of the actual life of the lamp. If it was just for room light,
who would care? But of course it's not. And of course, you KNOW this, I am just reminding you. How was
that last algae outbreak, lol. You KNOW reef-keeping is ridiculously expensive. Pouring perfectly good salty water
down the drain, lamps, replacement corals and fish for all the ones we kill. It's hell,
Sadly it's just about time for me to have to change out lamps, too. I save them though, in case I ever need to
grow weed.
