Bulb is about as bright as a 44 watt halogen flood bulb at maximum dimming. This is not really as can be "dimmed" call, then she goes out abruptly. At full power, it is very light, but the light is not very cozy, very strange, especially in the dimmed state, blue / yellowish. So you have to do a lot, so these things can replace the standard light bulb is technically very.
