lumicycle halogen mods

[kblackburn]

Hi Guy,s

i've been reading most of the threads, regarding mods to maglite's and others.
I've managed to get hold of a single lumicycle halogen light, all be it without a battery pack, and would like some input on converting to led, i also got hold of three tesco 3 watt cree lights, which i intend to make into a helmet light with remote battery pack.
I thought i might run the lamp, halogen for the time being, but after trying it, find it too yellow and dull, compaired to a cree Q5 200 lumen light i bought through ebay
So what do you think will fit into the lumicycle lamp unit, to give me a good amount of lumens.

thanks in advance

Literally this morning two DX 35mm reflectors arrived - I was pleasently surprised to find they have a pill attached - They fit spot on in the Lumicycle housing - although they are a tight fit, the socket needs to be replaced with a flylead. In there with a Q5 & 3x7135 driver at the moment, should be c.200 lumens I reckon. Certainly the same output as your Ebay one. if you wanted to get really silly with it, I've no doubt an MCE would fit with a bit of dremelling - and even though it'd be pretty floody, 350 lumens should be readily achievable - You-ll be limited basically by how well you can get the heatout.

herulach,

thanks for the response, could you link the part numbers for the reflectors and the led, just so i can see what to look for, the lumicycle halogen can is the cylindrical version, i was a bit worried about the usable depth, with the switch and power input, as far as heat sinks go, my brother has a lathe in his garage, so i might be able to produce something to fit within the case.

herulach,

forgot to ask, what did you mean when you said it had a pill attached ?????,
sorry, but all this electronic stuff is new to me, but i'm willing to learn.

Best conversion for a Lumi Halogen can i've seen used a Cutter Boost kit and a 5mm (iirc) aluminium backing disk cut to be a tight fit into the tube. The backing disk acts as a thermal path to transfer the heat from the cutter board into the light can and away in the breeze.

The Boost kit will allow you to run a 3xR2 setup on a standard Lumi 14.8v Li-Ion battery - around 600 lumens and only half a dozen spots of soldering to do!

Reflector ID is 14519, the pill is the bit that screws in the back to mount the LED & driver on - i was expecting to have to cannibalise a P60 drop-in. I've got a cree Q5 running at c.1A in mine, and for me the housing gets warm enough.

Depth won't be an issue with the cutter kit. You can fit the whole lot in the Lumi can with ease. If you have access to a lathe, I'm sure you could come up with something custom.

herulach,

found the cutters kit with the link, but cant work out the cost, there seems to be 2 types, high and a lower powered one, it states $75.95 but when you go to the cart it becomes $127.00. i would like to convert but don't understand why theres a price increase, may be i'm looking at it wrongly, can you shed a bit more light on it, on the other side if i opted for the low voltage option what run times could be achived.
thanks for your input

The buck/boost option is dependent on your battery. If you're going for a 3 LED board, then the forward Voltage of the LEDs will be about 11.1V, so you need a buck board for a 14.8V pack, and a boost board for 7.2V ones. The price is probably because you chose different options - the price changes as you add odds & ends on.

Have also seen this heatsink on ebay

Should fit around the lumi housing if the dimensions are correct, perhaps cut in half. Your problem then is to get the heat from the LED to the can.
