Question for the Electricians / EE dudes

[Dustin Mustangs]

I am trying to source a small, waterproof flood light that can be run off the battery in a ski. The cheaper the better, but it has to be able to put up with the constant impacts associated with surf riding. I also want a small enough draw that it won't cause issues with killing the battery. It will be used primarily when the engine is running and no, this is not for riding at night.

Where can I find something like this and what types of specs do I need to look for?

leds?

send a pm to WB800BLASTER

 

[AtomicPunk]

LEDs are on the right path (impact resistant and low current draw) but how much output are you looking for?
Because "flood light" and low current do not really go together...

what he said

You can get High Intesity LED's. This is what is used in the little flashlights, tap light etc...

 

[Dustin Mustangs]

I don't have a set in stone requirement for output, but the more the merrier. I used the term flood light because I want it to light up a whole area from a short distance, not just one little concentrated spot. Does anyone know how much unused amperage a 62t charging system puts out? I like the idea of LED's and I guess the number of which will be determined by what the skis charging system can handle. Also, are LED's waterproof or am I gonna have to come up with some type of waterproof housing???

 

[AtomicPunk]

LEDs themselves are waterproof-ish but you will need some kind of housing, circuitboard, etc... you can get individual LEDs with different dispersion patterns (wider or narrower)

To get enough light most likely you will need something with mulitple LEDs,with a lens (similar to the LED bulbs that are available for home use)

For something "off the shelf" these might work, but not cheap:

Use the battery powered Cree LED headlights http://www.ledwholesalers.com/store/index.php?act=viewCat&catId=55

I think I found something that will work but it's out of stock...

Still wondering how many of these I can safely run. It says .44w per piece. The standard 500gpm bilge draws 2 amps and some people run two with no battery issues. So 4 amps @ 12 volts = 48 watts. Correct? If so, I could run 4 or 5 of these with plenty of room to spare!

What are you going to do with these? It might help with the input if we knew what they were for...

:dunno:

Man go to walmart and get a set of small driving lights in the auto department. 12 volts, done deal. Make a mount and your good to go.

If your not driving around at night I dont see the need to be waterproof.

I am looking for a way to cheaply and safely light my engine compartment w/o bringing another battery on board. I have a HD gopro on the way and am thinking an 'engine cam' might make for an interesting angle during certain tricks.

Good idea...

 

[Matt_E]

Use a couple of LED flash lights fixed to the inside.
No reason to get all fancy and power it off the charging system.

 

[Dustin Mustangs]

Trying to save weight and money but that may end up being the way I go with this...

 

[Matt_E]

Weight considerations arent' the first thing that come to my mind when I think LED flash lights.
Money doesn't, either.

maybe it's just me - but what are you going to see with an "engine cam" shot?

only thing I'd think you would see is the engine revving up. With no prospective to the outside - it's just an engine sitting there revving.

 

[BombThreat]

would be cool seeing it flex when a ski lawn darts

 

[BruceSki]

you'd be surprised how much it moves around in there. i think this would be interesting to see.

go for it with those little lights mick showed taped up to the hood or something. they are very bright and weigh less than a pound each.

no way man, it would be sweet to observe how much the engine moves during a bail or landing after some big air
