I can't put back in the reflector, just the lens cover and cap, any ideas what to do to stabilize the LEDS?

Used a little hot-glue to keep the LEDs straight and forward. Also, put resistance of 7.33 Ohms on the battery, so each LED theoretically should be pulling 60-80 mA's

Axolotls,

Three questions:

How did you connect all 4 LEDs together so that you could insert them into the bi-pin socket?

What's the beam like at at say, 10 feet away? Would you recommend it over 2 LEDs?

What battery or batteries are you using?

I like N cells for AA flashlights because of their 1000 mah capacity.

Cool light. I also use hot glue for a lot of my projects. Maybe try the high temp glue for best results.

Some glue guns are low temp or high temp. Some are both. You just buy whatever glue sticks you want to use it it. The high temp sticks have a higher melting point so if your light gets hot you might remelt the low temp glue. The high temp glue should hold up to any LED project just fine without getting soft again.

This took some time. I got four 5,600's and bent all the pins 90 degrees from the base of the led. I connected them all in parallel by intersecting all 4 leds (8 wires) and soldering all the positives together; same with the negatives. I had to use some sort of spacer because one of the positives crossed on top of a negative. I then re-bent one of the positive and one the negative leads back to vertical (parallel to the led) and snipped off the other leads. Then I stuck it in the bi-pin socket. After posting this message I used a hobby hot-glue gun to seal the leds to the base. No problems thus far.

I posted on whiteleds (oh, hey that's you

)that the difference between the single led and four-led is not amazing. The beam is a bit wider and the color is 'whiter' (but not necessarily brighter). Brightness-wise not a whole hellava lot of different. It was fun, but not practical. I would say that if you messed up a bunch of led leads, this would be a got use to put them to.

I used the 6-V LR544 battery; but since I've been playing with it the voltage has been dropping so I dropped a 544 (1.5V) in there to compensate. There is so much room in there I suppose I could keep dropping in 544's for quite a long time before the mag holder fills up!

Because of the low capacity of the 6V, I will find out what's more cost effective for my wallet. So 3 N's or maybe 123's whatever is cheaper.

Cheers

Is that the same as my little stanley hot glue gun? This glue actually is good because if I make a mistake, I can peel it off a few days later without any damage to the components.

Also, just took out the 5,600 from my single led mag and put in the 20,800 blue-green led. But frosted the led with a 600 grit sandpaper. I like it!

Axolotls,

I've been thinking about doing a multi LED Mini Mag myself but I'm wondering how did you get the switch to work without the reflector in place? I looks to me, unless I'm missing something, that you have to have the reflector in place to push down on the switch when you rotate the cover to the off position. Let me know. Thanks
