9 watt Luxeon's for DIY bike lights

[trotts7]

These bulbs (see link orattached pic) have recently (i think recently) become available on ebay. Has anyone had any experience with them?

60 degree beam is way too wide.

I have not seen the ones you are looking at but I thought that 60 degree was too wide beam spread. I was considreing the one in the link below. Seems purpose made......

There's also a 20 degree model as well. I was thinking 20 on the bars and a 10 degree on the helmet. Could be the business.

Yeah 60 degrees is way to wide, however the stats read that the individual lenses (this light has three) have a 15degree spread, it might be a case of re-alligning each within the light head to point in the same direction (surely it wouldn't be that easy).
That ledshoponline bulb is a 3 watt, does look good but 9 watt would have to beat it.
