where to buy 18w bulb??

[Omicron]

Welch Allyn is pretty much the only mfg. of those bulbs - doesn't matter what light you have (Halcyon, Dive Rite, UK) - it's a WA bulb in the light.

Unfortunately, they are EXPENSIVE!!! We were looking at buying some replacement bulbs from WA directly for our Dive-Rite light heads (as backups...) but the price wasn't really any different than what we could get directly from Dive Rite. If you start ordering bulk, you get discounts...but who needs 100 bulbs??

Good luck on your search - I know a lot of other people are trying to get cheaper bulbs too, but it's not really possible to save a ton of money on these HID lights - it's one of the things you have to accept when you buy one of these - just ask my dive partner that had to send both of our lightheads into DiveRite after he blew them w/ reversed polarity on a battery!
