Are there any mods or upgrades for the UK Lightcannon 100. It uses a $85 10W bulb, I was wondering if there is anything brighter or cheaper for replacement.

I haven't found a replacement bulb any cheaper--this is a Welch Allyn I believe and of high quality and used in some custom lights.

Hello ADDICTED2LITE,
The UK LightCannon HID is very well made and i personally highly recommend it.
Rated 450 Lumens and it spectral range is cooler and i believe it may extend
slightly into the UV range according to a post i read on the WWW. Scubaboard.com.
Waterproof to 500 Ft
up to 1000 lamp life.
Burn time :3-4 hour, Alkalines, 2 Hour Nicad Pack.
I suggest checking out WWW.underwaterkinetics as well as WWW.scubaboard.com
for reference.
Most of what i have been told and read has been positive about the Light Cannon.
Its recommended that when it is turned on leave it burn for about 3 minutes before
turning it off and wait another minute or 2 before re-striking.
This is on account of the HID bulb which is also fragile and careful not to drop or
bump the light too hard.
Be careful with on line sales, sometimes theres warrantly limitations.
Undewater Kinetics is very reputable and is known for their well made lights and
customer service.
I have a UK C8 eLed Plus and although its only 170 Lumens its real bright!
The UK Light Cannon can also be used out of water.
One more thing,,,, recommend using Duracells with this light.
I heard it does not like energizers!
Happy Diving, or illuminating, PARIS.

I'll second the "don't drop this light" from above.

It's a great light, especially for really wet/ diving situations. I like mine, just didn't like having to buy a new bulb when I dropped it.

this is a dive light, outside of the water its very concentrated imho,
maybe try to change reflector position for increased needle beam.

and: NO, there is no bulb upgrade!
man this is a HID light! You cant swap any other bulb in like with Hotwires, You would have to change the ballast and the bulb for modding the output.

but if You are able to do this, AND find the space inside the light: put a regulation circuit, set at the 10.2 Volt nominal input voltage of the ballast, between batteries and ballast
I almost never used my LC because the output was soooooo awfully blue and dim (compared to what I thought it should be).
No matter what batts I used, direct driving the ballast gave lousy output.
Now, with my bike light mod (bulb and ballast and circuit inside a cutdown flashlight tube) already almost finished, the same setup, but getting the needed 10.2 Volt, is a very nice and bright white light.

PS: in the woods (and with some divers also, as one reads at their forums), the beam of a HID is not very good. Its only the less current draw what speaks for this technology. You dont see green, brown, red very good.
Thy such light out before getting one, maybe You cant stand the light color

The Welch Allyn 10watt HID bulb and ballast are already top of the (10watt-) bill !! No other brand has yet reached the performance of WA in the 10watt region !

Nice light but you will be sorry you did not go with at least 21Watt HID. I used to dive with a Nocturnal Lights SL-50. Poor quality, poor service but with a 50 watt So-Lux 6300K MR-16 lamp in that thing it was twice as bright as the dive guides UK Light Cannon. Check out Nocturnal Lights web-site for some good information on the difference between HIDs and incans. You will be happy with a 10 watt HID.

The Darkbuster is 5 times the light the UK Light Cannon is. I see 18 watt versions of them going for about $289. Batteryspace.com sells the 21 watt version but because of the 4 inch reflector it puts out more light than that my 24 watt Microfire 2000R or my 24 watt Wolf Eyes Boxer.

I just bought a Polarion so My Darkbuster is for sale. Just bought the Darkbuster last year and have dove with it about 35 times. It is awsome to have that much light in the deep blue at night. You see things that you never would with lesser lights. $275 and it's yours. I would have never seen about a 16 foot Tiger that was about a hundred yards from our dive group without that light. when we got back on the boat there was not a person in our group who as not committed to or thinking real hard about buying a Darkbuster.

If your a vaction diver, buy the UK. I said above that the divemasters usually have a U.K. It's what they can afford on $10.00 an hour and the the cheap tips most vacation divers leave. But ask them what they get if the could aford it.
