LED Intensity

there is also the factor that constantly running an LED at 100% will cut its lifespan almost in half.

That makes sense, but when the industry is stating X number of years worth of life, at what intensity are they rating them?

its lifespan is determined by running at 100%.
what i think you mean running them at a lower percent will increase life.



I'm curious as how long till the spectrum starts to change, if at all.

I "Heard" once 5% per year at 100% but I am sure that not accurate, and could be more. also depending on the types of features you use (I.E) thunderstorms etc, it could cause varied results IMO.

The way I approached buying my SOL's was sort of trial basis. I only ordered one the first time, I was 90% certain I would need a second with a 48" tank but with shipping being free for one or two I decided to see what one unit looked like. It took about five minutes to decide one was not enough and ordered the second. This same principal will work for anyone even if you had to start with say 3 or 4 and add units if needed.

kinda my plan as well. I"ll start with 3 and see how that goes. Problem I have is that the tank may suffer before I can afford to buy more.

Just wondering what is the difference between one 3w LED and the other?
Other then dimming and fancy controls what is the difference between AI sols and these

?
They have single fixtures 5" wide and double fixtures 9.25" wide. If everyone is running their "fancy" LED's at 35%-50% anyway?
Really want to know what is the difference. thx

Just leave your existing lights in place, when the new ones arrive just get a bunch of people together to do a mock up and hold the lights over the tank for you as you sit back say "okay a little to the left, now up..no no the other up, you know down" All the time adjusting intensity to see how you like it. If you decide you need more units the original light is still there until the other unit arrives and swap out then.
