This will give me 9 watts and a whiter light. Then there will be an issue with heat. The included heat sink is pretty massive, but there also has to be a drain for when it “fills up” Better thermal contact of the sink to the head will help. As of now it is not an issue.
That star is too big, it is 50mm. Mine is 32mm as shown in the pic. I saw that too at fasttech and would love to find that cree q5 in a 32mm star. instead I ordered 6 3W bridgelux from them. In quantity they are .66 each - cheap enough! I am looking forward to seeing how fasttech does with my order, they seem to have a very good site.
Pure flood, and warm white approx same color as an incan. Now that I know this works, I will do a cool white version. I don’t know what degree the TIR optics are, but it is floody. Output is approx 270 lumen so there is more light that the LED mag which is around 130 lumen. As I said, I will next try 3 –3W BridgeLux emitters @6000K on the star. They are only 66 cents each at fasttech in quantities of 5 or more. So my mod cost is soaring!
$2.24 + (3 x 0.66) = $4.22
