Looks like you'll get a nice floody beam from that MC-E perfect for bike riding.
I'll only mount a P7 based light or an MC-E on my bike.The output rivals a cars headlight. How hard are you driving that emitter?

The eternal question : Where are the beam shots?

Oh, and :welcome:.

hi,

on weekend i make some beamshots,

here some facts about the hardware:

driver: hipflex from taskled @ 2.800mAh
led: cree mc-e parallel mounted
refli: ledil boom SS
weight: 130g all incl.

i use thermal pad material to transfer the heat to the housing. that works good. the hipflex runs on 70C.


battery: 11,1v LiPo accu in a bicycle bottle with 10.000mAh



the refli works great with the mc-e, no donut hole and a nice flood beam.

actually i think about using this light as a headlight on my bikehelmet.

 

[Doh!Nut]

11.1v * 10,000mAh = 111 Watt Hours.

Thats over 10 hours at max power

If you ran it as a helmet light you could use 7.4v *2400mAh which would give you an hour and half on high and much longer on low.

I find the weight of two 18650 Li-Ion cells OK mounted at the back of my helmet.

ps Nice even colour in the anodising
