entschuldigung. meine deutsch ist slecht. aber Sie können im deutsch antworten.
I am trying to upgrade a (dive) light from halogen to LED.
In first I just replaced the 2 halogen (20+35w) bulbs for 2 (2,5w) LED bulbs but the output of light was not satisfactory. The burn time was way beyond expectation.
Talking to various persons about this the outcome was that this kind of modification does not work well. We even talked about just modify just the bulb but with the new high power LED the heat must be taken care of.
To make it work I designed a heatsink that fits in the housing and will be sealed by x-rings (the way it was originally designed).
So now I need to find someone to fabricate this for me.
However, I still have some questions (I am handy but I don’t have the expertise of choosing/combining the right electrical parts).
I am thinking of putting 2x 10w HP leds (high Lumen), which I can (thermo)glue to the heatsink.
Enclose the proper driver or drivers (if needed also (thermo)glued to the heatsink on the other side of the LED. The height can be max. 22 mm
The grayhill rotary switch has 4 connections (OFF, LIGHT 1, LIGHT 1+2, LIGHT 2) but if possible (depending choice of driver) I want to change this in: OFF, LIGHT 1/50%, LIGHT 1+2/50%, LIGHT 1+2/100%.
The battery pack has 13.2 v 4500mah. (11 cells).
If Can you help me with which parts to choose? And a wiring diagram, costs.
I can send the drawing of the heatsink so you can have an idea of what the plan is.
Thank you very much. Paul
