This GENSSI III is an interesting bulb since it seems to be a clone of the first Philips LED bulb. It has a few issues but is good bulb for evaluation. The main issue IMHO is that it has no fan. It uses 22 watts measured for both low and high beam. On the bench the circuit board got to 130 C at room temperature with just still convection air. The max operating spec for the LEDs is 135 C. If you can mount it where it will get air flow you might be OK but do not think about stuffing it in a box. I mounted one on one side of my ST1300, the other side has the Evitek G6 so I can test it out. if Keep it I will put a small CPU fan or salvage a fan from another H4 led that I will never use. The second issue is who ever designed it put the twist into the two shields but got it backwards! It would be fine if you drive on the left side of the road. So I did a little filing and added a bit of aluminum tape to even out the pattern. Later I might fabricate a better shield... I like the ability to adjust the twist but they should have made the shields symmetrical. It is a little harder to mount than the G6. (end of buyer be aware) What I like about it is that it has 4 small leds in a row that better emulates the halogen bulb (the original Phillips used only 3 leds and it was way too expensive to test). I wanted to see how this compares to the G6 bulb. It seems to have about the same lumens as the G6 but the pattern will be different. As I expected the Genssi III projects a thinner line on the wall compared to the Evitek. More of the light is focused on the horizon. Good cutoff. (will make DOT happy) The Evitek G6 with its slightly wider line is fantastic on a remote dark road. I think the Genssi III will be a smidgen better. But better might not be the best word since this will become more of a difference of user preference based on riding style. Gee it is great to have choices. Let the testing begin. I just got the bulb give me time to get some more data. Now again lets keep this thread technical or philosophical (which beam pattern you like better and why). No bashing vendors please. Lets just give good usable feedback so that we can get better products and help our fellow riders. I am not a vendor, just a rider looking for the right stuff...
