Hi, sorry this is a fairly n00bish question, I've only recently discovered this forum and plan to do plenty of homework on here before building my own lights, however:
I've been given the parts to a Cannondale HeadSight by one of my customers. From what I can gather, it's basically an Exposure Joystick MaXx in two parts - a battery and a head unit. The two have been pulled apart (a thief attempted to pull the light off before realising it was attached) so I've already done a bit of soldering to attach new cord and power connectors. He gave me the charger so I've tested it - it charges fine and runs fine, has two "on" settings (high and low) and a flashing setting.
I've taken the front off and the LED says "LUMILEDS" on the emitter side and this on the other:
So it looks like a Luxeon LXHL-LW3C, a 3W LED. To finally get to my question (sorry): is it possible / worthwhile to simply replace the emitter? It would be pretty straightforward to unsolder the current emitter and solder in a new one in its place without changing the other electronics. I'm wondering whether this is worthwhile, if there's a more efficient or maybe brighter LED that I could replace it with, without harming the other componentry.
I'd be interested in any advice you could offer. I'm capable-ish with a soldering iron and a multimeter but I haven't yet learnt enough from this forum to do all the legwork myself, sorry!
