As I am now producing my own lamps, this page has been re-written. Of course there are lamps, and there are lamps.

For the past 6 months I have been experimenting with Oldham conversions of my own design, with some rather startling results. Basically, I have produced what could well be the worlds most powerful caving and mining caplamp, capable of sustaining maximum output. It will power 4 Cree Q5 emitters at maximum power to produce well over 900 lumens. The core problem with anything like this is getting rid of the heat produced by the LEDs, my design utilises a copper thermodynamic conductor and external heatsinks. There is no doubt at all that it works, and I soon expect to be producing my own lamps. I am currently using a model that produces half this output, and that lamp beats everything it comes up against including the mighty Scurion.

The pictures below say it all, the first is my car with headlamps on main beam and engine running, basically everything is on, main beam is main as well as main. Its 350 watts of quartz halogen. Below that is a Fellows MagnumStar Oldham caplamp conversion. Estimated output is well over 900 lumens. These will soon be on the market for less than £200.
