2D Mag mod 5x Cree R2s

[ecotack]

I saw ASDA was selling the 2D Mag quite cheap, so I ordered a couple. I had seen the 5 LED reflector on DX and thought it would fit the Mags. It took ages for DX to get them in stock, so I first made a 4x Cree R2 version using a 4 way lens again from DX.

LEDs are in series and I am using a MaxFlex driver. I added a second button for the mode select and because this button was semi translucant I placed the LED warning light behind it (to warn me when the batteries are low).

I was originaly going to power it from an 8AA battery pack, however my GP AAs where two big to fit without boaring the Mag. I found the Eneloops would fit in (just) with my home made adapter. Unfortunatly the Eneloops voltage dropped to much when trying to drive the LEDs over 700mA.

I finaly settled for 3 Li-Ion C cells, unprotected, but the MaxFlex driver warns and cuts off when the battery voltage is low. I removed the end cap spring, sanded off a contact area in the end cap, used a piece of perspex tube to hold the batteries in place, needing to add a couple of 8x1mm magnets on the bottom to make a good contact and the spring in the Mags switch holds everything nice and tight.

Torch now setup for 1200mA on high.

Interesting mod! I have the same light in the works... except mine is a cut down 4D and will run off 4x C-size li-ion cells.
It would be interesting to see some beamshots!

I agree, I really need to get out one night with all my torches and compare them.

Next project is some 5 watt LED tail/stop bulbs for my TVR. The 3 x 1 watt bulbs I bought are not bright enough. That is when DX send me the driver boards I ordered. I also need to finish the 12v lighting for the stables before winter.

I've been thinking about a multiple MC-E in my other 2D, using two D Li-ons and just the cheap 2.8A KD drivers. I think 5 MC-Es would be to much, probably need 9A from the two cells. Perhaps 2 MC-Es and 2 XR-Es to fill in the doughnut.
