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!!
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
