Best cooled LED light?

[Douglas.Curtis]

I doubt a 5 year lifespan.
I used lamps with cree, osram and so on. Mounted in fixtures with fans and fins and so on. Worst of them, i could meassure more than 20% loss after 1 year. Spectrum out of order too.

Technology has changed significantly in the last few years. The newest ceramic based chips have a less than 10% fade in 10 years of 12/12. The failure rate is also much lower.

You're going to like the newer lights I'll vouch for the Mars Hydro TS series of lights, I have a TSW-2000 and love it.
