  • Great replacement for 30W halogen

    posted by ofsilence on 10/09/2012

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month


    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.)
