Hi,
New to the forum and thinking about building a nice headlamp for running and mountain biking. Hoping to get your input on some ideas! Will post progress of this project in this thread.
Looking to output about 4000 lm so my initial idea is to use 5 pcs of the Cree XM-L2 with cu base outputting about 800 lm/pc. To start - is this sensible in terms of realistic output? See below.

I would like to use small <20 mm diameter reflectors for the 5 leds with varying output angle - can you recommend good quality reflectors? Maybe even an initial setup? I would like these to be exchangeable so that I can change the angles of output. Initially looking for a nice wide beam but also a long throw in the center, hence 5 leds.
On the electronics side I'm in real need of help!! I would need your recommendation on a driver and hoping to have low/medium/high output with the high output lasting ~2hrs. Any ideas? Needs to be ready made as I'm not good with the soldering iron (connecting the leds will be a big enough task!).
The housing will be machined out of an aluminum block (will post images as soon as the first design is finished) but need some of your input on the above before I can finalize the first draft.
Thanks!!
