A very natural light and good coverage, what's the life of these bulbs Jack?

And roughly how much did this project amount to?

They have a lifespan of 25000 hours when operating at full voltage and current, I'm running them slightly under power so I'll get a little more life out of them, but there are no significant output drops in light until just before the very end of their life.

In total the unit has cost £25 to build, £25 for LED's, heatsinks, driver, power supply unit and thermal tape, the wood, solder and fixings etc I had already, I just need to fetch a little more wood to box it in and then reduce the glare from the LED's, I'll probably add some collimaters to them, which are a bit like reflectors.
