Patric - The Malkoff dropins are much brighter than the MagLed. I can't compare them to the Terralux in a 2D, since I don't have the model you are interested in.
I can say that the Malkoffs are really bright in a 3D or 4D. I have a MagLed in 4D and the Malkoff makes it look dim.
Runtime won't be as good, but the light is much brighter. I don't have the time to do runtime tests, but I do recommend the dropins. My 3D uses a Malkoff stippled reflector and it produces lots of output with adequate throw. The 4D has a smooth reflector and it will light up a house that is more than a block away. It has way more throw than the MagLed, and a wide spill that is useful for walking. It is dark in my neighborhood at night.
