LED Growspot Light Flashing
I've been running a small hydroponic garden (Emily's Garden) for about 9 months now, using a CFL and a Growspot 12w blue light as my light sources.
Things have been going pretty well, but just last week my Growspot 12w started flashing a few minutes after I turned it on. I tried switching the fixture, but the light flashed in the new fixture as well.
I'm thinking the light might be about to burn out, but that seems crazy given that it has a heatsink on the base and that I blow a fan on it for most of the day, dissipating any heat that remains.
Generally I leave the light on about 15 hours a day- 12 hours with the fan and 3 without.
Anyone have other suggestions about what this might be? It's a fairly expensive light (for its size) and is supposed to last something like 20,000 hours, so it's a bit of a disappointment if this is just the end of its life.
