A few weeks ago while sorting out my room, I've found my old OSRAM Mini combi, but sadly, with the fluorescent tube broken and the halogen bulb missing..It was a good flashlight, with both floodlight and a halogen spotlight.
The original flashlight looks like this:

Being in a LED torch community, I've decided to modify the flashlight, with the fluorescent tube replaced by a 3W strip LED and the halogen bulb powered by another Luxeon Rebel drop-in I've made
The torch was originally powered by 2x 1.5v batteries, with made the strip LED seems under-powered, and the battery drains out faster. So I've added a maxim 738 circuit. The battery output becomes 5V, and the circuit fits the torch nicely too! Then I secured the PCB to the torch with clear epoxy.
I've also added a magnifying lens (salvaged from other illumination equipment in my workplace..) by cutting a circular hole on the plastic front cover and securing the lens with clear epoxy.
And the results:
The spotlight:
The new floodlight:
That's all folks! Thanks for viewing my post!
