Good morning guys,
I joined up this morning looking for feedback, experience and opinions on retrofitting consumer LED light bars with high powered LEDs. Just a bit of backstory I have been very much into lighting since high school and I seem to come across a new flashlight I have to have in my pocket about once every 6 months. The last light that I added was a klarus g20 with a XHP70 emitter.
I started with a 6 lens “8D” led lightbar from amazon ( I know cheapo lightbar ) but I figured the convex lenses might handle the larger sized emitters better than a traditional reflector. Tore it apart, measured the spacing between the existing emitters and pulled the control board out of the bar to make space for the XHP70.2 stars. I mounted the stars with thermal epoxy and screwed them to the heat sink and soldered them to 2 copper bus bars running the length of the LED.
For control Im running a no name step converter with a current limit of 6a so I will be driving the 6 XHP70.2s at approximately half of their maximum rating until I determine how well my inexpensive lightbar holds up to the additional heat.
At the moment I am about $120 into this build and by the end of the day today I hope to have a few example beam shots.
