Hi! My first post, even if i have spent dozens of hours reading this incredible forum. Thanks to all for everything i learnt.
As i bought a scurion some time ago and my old duo (bulb version) wasn't working anymore, i decided to put inside a couple of seoul P4 and drive it with 18650 batts.
I glued a heat sink and a piece of aluminum and "took them out" of the housing, sealing the hole with "aquasure", wich glues well to plastic and metal and guarantees watertightness.
I used two 5 mode DX drivers (just because i had some spare ones of previous experiments) and a three position switch to control the two leds, wich use a 6 degree and a wider one (¿?) carcio lens, for throw and flood.
I also made some place in the battery case to allow 3x18650 (3.7 V) to fit inside, connected with a JST plug.
Using it in medium mode (aroun 300 mA) gives a very good light for general caving and keeps the light at a warm temperature (not hot at all) getting more than 7 hours of light from a single 18650 (i stopped it then 'cause it was enough for my test).
The throw of the 6º lens is quite similar to the scurion at high.
When running it at high mode, the heat sink gets hot after some minutes and probably the led is suffering, but i plan to use it only for short periods (some seconds or a minute) so no matter.
Pics: (it's a crappy work, but works 🙂)
