For other lights I build my own from parts here:

I've built quite a few LED lights myself, but mostly as small room table lamps to work with my 24 VDC emergency home power supply. One thing to keep in mind, no matter whether one has the 150 or the 200 lumen model is that it is might be wise to avoid running the light on the highest power setting unless that small bit of extra light is really needed. A maker can push the LED hard, or run them more conservatively. Power consumed is proportional, but when the LED is pushed hard, the PN diode junction will degrade from generated heat. The light will then keep sucking a high power, but the light output will gradually decrease. Push the LED REALLY hard and it will blaze like the sun, but only for a few minutes until the diode junction melts.
