QUESTION Expected Lifespan Of a Power Supply ?

Let's say A 300-watt power supply is used. But only a 280 watt constant load was applied to it, in this case of course LED's. Any guesses as to lifespan? in hours or years? Max ambient temp of 90F....

Peeza Cake Mr. Wizard...

Now the "10" volt LED project is involving...
(2) silicon and 1 shottky series diodes should get me where I want to be voltage wise. The star fin heat sinks (90X10 mm) will allow convection cooling without a fan. But trying to find individual heat sinks for the 30 watt chips is a real chore.

Don't forget I've got the Ammo box charger thing creeping alon waiting for parts. Exterior 12 pole switches replace the MW trimmer pot. Couldn't resist adding a kWh meter
