So many new lighting systems, who's buying them all?

It's also amusing to see the move back to metal cases as the LEDs increase in power. Love those external heat sinks that they try to blend in as part of the industrial design on "http://www.performancebike.com/shop/profile.cfm?SKU=23115&subcategory_ID=4320". Maybe they can do a heat pipe and use the waste heat for some sort of heating system for winter riding. I have the single version of this. I've never felt the heat sink get warm and with the effect of air flow across the pod as you ride, it is hard to see how it could. However, with all the circuitry housed in the pod I think the heat sink is a matter of just in case. If it offends anyone delicate sensibilities, I think the entire heat sink collar comes off with a single screw. |

If you're going with the wind or standing still at a stoplight, for example, there will be pure convection cooling rather than forced-air, which might well make the heatsink a matter of necessity.

Still, I got to wonder how much of that "heat sink" look is technically necessary, and how much of it is dramatic design for marketing purposes. Pat Email address works as is. |
