possible to replace bulb on L&M Arc HID?

Hello,

My Light and Motion Arc HID bulb gave up after 2.5 years of worry-free usage.

Does anyone have had success in dissasembling the L&M lighthead and replacing the bulb? I had a quick look, and noticed that the lighthead has no scews. Anyone has any ideas on how to proceed?

Thanks!

Try sending Slovid a PM, IIRC he has disassembled one.

Did you manage to find a replacement bulb locally?

No. I was thinking about ordering one from Batteryspace. If the bulb is user replaceable, I would save on shipping to US (20-30$?) and L&M service charge (40$).

Verners might have one locally.

Doesn't the arc have a custom aluminum reflector?
The lamp from Batteryspace would be different than that. It has a glass reflector for one thing. I'd be surprised if it fit.

The idea is to buy a bulb with a reflector (if buying from Batteryspace), then throw out the reflector. Of course, this is feasable only if it's at all possible to open that lamp.

Well, yes, and I also assume that it's possible to remove the bulb from the reflector. That should be doable.

I don't advise it.

You CAN open up the lamp from the front. The little bezel piece comes off and then the glass comes off rather easily. The reflector is proprietary and a good part of their success. I haven't had my mitts any further into this thing, though.

Is there a way to tell if an HID light is near it's life-end?
I didn't think so, but I've noticed the inside of the front protective glass getting more and more hazed over time. (This is a TrailTech sourced bulb)

I don't think it's possible. I have a TrailTech with that bulb, I've had it out and I'm pretty sure it's a completely sealed unit.
