    L&M bulb replacement alternative

    I have a nimh arc with a blown bulb that i inherited from a friend and was planning on getting a direct replacement but my LBS was quoted $150 for the bulb alone. Are there any alternatives? The difficulty seems to be that the arc uses a standarc solarc ballast but due to the separate reflector uses a non standard bulb?

    Try calling L&M directly. I've heard some phenomenal customer service stories about L&M.

    It's a little cheaper ordering direct (and I mean Welch Allyn, not L&M):

    So is that the same bulb? Can the casing just be taken off as the original just has the bulb as far as i can tell?

    Yes, it's the only 10W HID bulb without reflector that W/A makes. And this is the ballast L&M uses in case you're interested:

    Thanks for the links homebrew, so is this the same ballast that they use in the Li-ion version or is this different? i was thinking i might use a 11.1v li-ion pack i have lying around depending on how long the nimh pack lasts.

    The brezel of the L&M can be unscrewed? I tried but without success.

    It's the same ballast for both NiMH and Li-Ion although I don't know if L&M add any additional regulation within the Li-Ion battery (maybe included in the protection circuit?). Here's the datasheet with all the info:

    http://www.walamp.com/lpd/files/data...evB_10watt.pdf

    The datasheet says maximum instantaneous voltage is 11.8V which a fully charged Li-Ion could easily put out even if it's just for a short time.

    Check and see what the price of a HID 13w bulb is from Trail-Tech for their MR-11, it's the same Welsh Alyn bulb.

    No, it's not. L&M is using the W/A bulb without reflector adding a custom L&M reflector. TrailTech is using the W/A bulb with built-in reflector. Again, see the datasheet referenced above for more info.
