Intova 3W LED Dive Light?

[vshearer]

Cool beans. Just saw this thread and picked one up off of Buy.com for $32 (including shipping).
Thanks.

Did you use any type of sealant when you reassembled it, or is it tight enough to just push it back together and leave it?

2 machined grooves in threads hold O rings, and a gasket at base ...
I used silicone grease on the threads/O rings to make sure that they dont want to climb out of place when putting it back together .. it takes some fiddling to make sure your not cross threading it when installing the head to the body .. just gently experiment with it, it will line up all of a sudden

can you guys post a side-by-side comparison once you are done "upgrading," this seems like a pretty cool project. What do you expect the burn time to be with the ~200lm LED?

...the thin key ring that holds the lanyard.

You would need to replace it as it is extremely frail....

Are we talking the same light?

I have no key ring on mine, it is a good lanyard threaded through a hole in a very strong look part of the screw off cap. I just trie ripping it off about 5 times, did not give a a fraction of an inch...

mine had a wimpy key ring in the center protrusion on the cap, if I keep the lanyard, I will thread it through one of the bigger holes around the perimiter of the cap

They must have changed it, mine is quite solid...

This is the one it has now ...

60Lum at 700ma ... Luxeon LEDs - LXHL-LW3C Luxeon III Star - White Lambertian

And these will fit ...

75Lum at 700ma ... Luxeon LEDs - 5027-PW12 Luxeon K2 Star - White, 75 Lumens @ 700mA

135Lum at 700ma ... Luxeon LEDs - LXK2-PWC4-0160 Luxeon K2-TFFC - White, 160 Lumens @ 1000mA

170Lum at 700ma ... Luxeon LEDs - LXK2-PWC4-0200 Luxeon K2-TFFC - White, 200 Lumens @ 1000mA

I just ordered one of each of the 75, 135, 170 Lumens LEDs (note: the 75Lum star I got here, #5027-PW12 is different than the one I had listed before, #5027-PW14 .. the PW12 is the one rated at 700ma)
It says it may take quite a while to ship some of them, I'll let you know how it goes

D_B; I went at the light this weekend, trying to unscrew the head, but no luck. Large strap wrenches, padded bench vise = no luck so far. So, is the head screwed on with fine thread similar to the tail cap? And sealed with a couple of o-rings?

It's odd that the head is on so tight on mine. I'm wondering if there has been a design change in the light; mine came with the lanyard threaded through the quite sturdy post in the center of the tailcap.

Of course, I realize that the head must be a separate part - no way to get lens, LED, control circuit etc. in through the tail. But really, when I look at the head/body junction, it might as well be one part, that's how tight it is. Maybe they've started to use thread locker or some such when assembling the head.

Where did you order the LEDs if I may ask?

It could be that it's that tight
Threads similar to tailcap, 2 O rings on threads and rubber gasket at base .. you can not see the threads but the large (2"?) part of the head with the machined grooves is the part that turns

Thanks for the info. How difficult was it to unscrew the head on your light?

I got to the point where I was afraid I was going to deform the battery cylinder of the light before I gave up. I'll give it a shot of PB Blaster tonight and see if it loosens up.

Suggestion: if you buy extra "star" bases without an LED mounted, you could solder your own complete stars and have an easier time swapping emitters.
