I have the square aluminum tubing, but what I lack is having a good clue on how to make these things water resistant, or at least somewhat waterproof (submerged for a few minutes if backing in a boat, and rain-proof).
I will definitely come up with something. Just what... I'm not sure lol.
I have an old beater utility truck I picked up for a sweet price over the Christmas holiday from some family. It's a 1990 GMC 1500. I do a lot of night fishing and have many times I have to back up my truck to turn around, knowing there is a 40 foot drop off behind me (followed by a 20 foot deep...
I figured something like this might be the case. I don't need the light to be waterproof, so some holes for passive heat dissipation wouldn't bother me at all.
I bought two of these today, mostly because of the battery run time (12 hours supposedly, I have one that's been running for 5 hours now on the battery's first charge and it's surprisingly bright for using cheap 5mm LEDs). I gave one of the drills to my 4 year old son for a fun toy (no battery)...
There are a few fairly light ballasts that can be connected to 110VAC that will run a few small LEDs. Originally I was going to use some very small light drivers (MR16 drivers) but I forgot those are 12v input.
I may have to do this, it's certainly simple. I could mount the aluminum (old CPU)...
I have a small stash of white LEDs (everything from Cree XML, XPG, Rebel ES, and chinese 3-watts) that are leftovers from me playing around with my reef aquarium lighting and a few utility lights I've built.
I'd LOVE to find a way to screw these into an edison-base light socket (non-dimming)...
I'm definitely open to that option. This is on the back burner for the moment because i'm graduating with my Masters here in a month, but afterward, I may do just that.
The main reason I like the Sipik is because of the adjustable lens--- I don't know if the L2 has that or not, I haven't...
You could probably get such a thing from Cutter, I may do it in the future.
I wonder how the new XTE (for royal blue) would perform in the Sipik. The emitter is a good bit smaller, so I expect it might goof with the adjustable beam.
For white, you might want to try an XML. They emit quite...
This go-around, my chinese orders showed up in about a month, which is fine with me in most cases and I'm happy with all of the lights I got. The Skyray was the biggest surprise, it's extraordinarily tiny and quite bright, the emitter appears to be an XPE.
Now that being said.... the thing...
Thanks! That's exactly what I needed :D
Now I just need to find the emitter on the right sized star. Do you know off hand what size star the Sipik 68 takes?
Also, I don't need a waterproof light, it won't be submerged (well, not on purpose lol). The coral are grown on the upper 8" of the...
I just received a Sipik SK68 (actually showed up as "HWA/WYS Ultrafire" but they appear to be clones).
Anyhow, I'm thinking of buying another and putting a royal blue emitter in it. The reason is that there is a local coral farm that I visit occasionally that uses natural sunlight to grow the...
I lost my favorite single-AA Cree flashlight that I used EVERY day, and now need to order another one--- something that's back-pocket friendly for a working man (I would consider a used one if you want to PM me).
I ordered them from DealExtreme but it took several months to show up because I...
Re: Problems with AA battery lights (DX stuff)...... won't come on easily.
Thanks guys. I'll clean the threads tonight.
The batteries are brand new, by the way. I replaced them when this started.
About removing the oxidation. Would flux paste for soldering work fine (Radio shack type)?
I have an Ultrafire WF-606A and a Romison RC-G2 that are both giving me the exact same problem. Both are the same age-- about 3 months.
In both cases, the light won't come on unless I unscrew the back where the switch is, nearly having to take it all the way off.
It comes and goes in spurts...
