Its color is warm, somewhere in the middle between 2700K and 4200K CFL - the most comfortable for me. Light is somewhat focused - the beam on the floor is about 1.5 meters.
Doesn't have the background spill. Not a con for most applications.
Very good cooling is provided by the heatsink. It gets only a bit warm.
illuminance, in my setup:
30W halogen 90 lux
this lamp 120-140 lux depending on distance from the center of the beam.
takes 320ma from regulated 12V source = 3.8W. Taking into account driver efficiency (yes, this bulb has regulated driver, also it works good with AC), leds should work at 1W each - shouldn't be overdriven = long lifetime.
Very good (and cheap!) replacement for 30W, of even 50W halogen. Energy economy is almost ten times!
I am buying 40 of them after I tested the one I bought.
The only thing should be taken into account - LED lamps work not very well with electronic transformers (main reason - very low comsumpting current.)
