If you are buying these for long life consider this.
The Cree LED emitters used here have a very good reputation and have proven to be long life units. Claims of 40,000 hours plus for the emmiters are conservative. The failure point is in the drivers. Heat is the problem, and since this design uses small fans to dissipate the heat, you now have another failure point. Fans and drivers won't typically go the 40,000 hours plus. The emmiters typically will go on forever if run cool....... Why buy a solid state light source that has to be kept alive by an inductive mechanical device. John |
