I like that design better because it utilizes a green LED, so you are not losing any light transmission when filtering white LEDs thru a green tube like I am. Still, mine will be plenty bright.

So that's 30W, or 2.5A. No big deal. Pretty inefficient for modern LED's, but cheap enough I suppose.

It will be in that range, yes. I haven't built the thing yet, so I'm not exactly sure (in the final stages of gathering parts). Since I had to buy 6' of acrylic tubing at one time, I will build more once I've got mine completed (until the excess tubing has been used up). I'll sell them just a little over actual cost. PM me if interested.

When I found out I could get those "bulbs" for approx $3.50 each, I wasn't about to pay $150 for one of these things.

And what would you use if you were building a cylinderacal submersible fishing light?

Ebay is the key. Approx $3.50/piece. Usually direct from China...shipping takes 2-3 weeks.

Do they work well and hold up to shaking? Boats do take a pounding.

At that price, I'd use those. Heck, at that price I'd use those for everything.

Mine aren't labeled as "1156s", but I don't see why any of them wouldn't hold up well. The LED "bulbs" are "wired" like PCBs. I could not tell you the manufacturer of the ones I have, but I have put them thru hell and they still test fine. Check out the link I posted earlier (of the bulbs that are similar to the ones I have), and you'll notice a flange around the base of the bulb, just above the terminal connections. I had to get rid of the flange to get the bulbs to fit in my tube. At first, I took wire snips to them. But that left the edge too rough, so I took a Dremel on 10 to them to cut more metal off and smooth them out. I hit individual LEDs several times and they still light up.

Go to Ebay and just type "1156 bulb" and see what comes up. Check out the prices, quantity per "auction" and see if there are any shipping charges. Also, check out seller feedback. I'm sure you'll find some good deals. Even if the bulbs crash earlier than you would have liked, you won't have spent much experimenting.

Also, given that LEDs usually have a life of 50K hours, I find it interesting that this is a cost you're concerned with. Are you have to replace them that often? That's like having them on for 5 years straight.
