Custom high power spotlight

Hi guys i would share with you my experience. I have realized two spotlights for my Jeep installed on the front bumper , each one is composed as follow:

 

1x Bridgelux V13-B, driven at 2.4A for about 13000 lumen; lens Gaggione LLC66N7 FWHM 20.9°

 

1x  Cree XHP50.2 HD (12V version) driven at 2.6A for about 3500 lumen; lens Gaggione LLC66N7 FWHM  8.9°

 

1x  Cree XHP50.3 HI (12V version) driven at 2.6A for about 3300 lumen; lens Gaggione LLC66N7 FWHM 7° (not sure)

 

For a total raw lumen of 39600 lumen (two spotlights)

I made the housing with aluminum flat parts and i add an heatsink in the rear. To control the temperature i use two NTC thermistor. In the following some photos of the realized units. Every comment or suggestion is welcome!!

Thats a solid build dude. What drivers did you use? Can you turn on the bridgelux separately from the two xhp50’s?

Thanks! I relized homade boost converters, one for the four XHP connected in series and other two converters one for each COB (my car voltage is 24V). Yes i can turn on the separtely the COB for flod light and the XHPs for spot. Maybe the light from the XHPs with this lens is far too spot

Some shoots of the lamp, the camera was set with fixed parameters( aperture, exposure, etc…)
