Outer Limits 4x4 Board

I have bought some Super cheap fog/driving lights to rig up as rock lights.
They have 55watt globes.
I am wondering are H3 globes available in a lower wattage than 55?
As far as I can tell all the globe makers only go as low as 55.
The reason I want lower is I plan on running 6 of these lights and 330 watts is going to draw around 23 amps and if you add headlights and spotties in it adds up to LOTS.
If I could get hold of some maybe 35 watts they would be bright enough as rock lights without drawing as much power.

What about running a 24 volt globe? does that give half the rated wattage @ 12 volt?

Why not use some dichroic lamps from low voltage domestic lights. They are 12V, available in 20w, 35w & 50w.
Various angle spread patterns available from 2deg pinspot through to about 50 or 60 degree flood pattern.
The lamps can be had for as little as a couple of bucks each. you can make your own lamp fittings for them using anything that is 50mm in diameter ( plastic towball covers work well ). I used these years ago to make headlights for mountainbiking after dark.
Just make sure you buy lamps with the glass lens.( if you splash water on one without the lens it will probably fail then and there).
