[Healeys] LED Headlight Conversion advice

[Roger Grace]

mmmm... well you asked for it ... !! 

Moss gives H4 LED at 25 W per light 
Typical halogen H4 is around 55W 
Thus a net savings of 30 W per light. 
1W = 1J per sec 
1kWh is 3.6 mJ 
So extra energy used/saved is 0.03 kW per hour 
= 0.108 mJ per hour 
using 35mJ energy content per litre of gasoline 
... mmm no comments about regular or hi octane please ! 
this translates into 3.7ml = approx. 2.5 teaspoons per hour per light saving 

So 5 teaspoons per hour net saving for both lights. 
Note this is just the electrical energy savings. 

So allowing 90% efficy for generator and say 30% for the IC engine likely net saving is around 18.5 teaspoons or 23.1 ml per hour !!

I am wondering what the energy savings would be between these LED lights and the standard sealed beam lights I now use?

Any idea of who besides little British carry the kit?

I bought the same pair of conversion LED headlights last week for $76.63 on sale with Little British Car Co. Sounds like the sale is over. Going to put them on my Bugeye.

Listers, 
Just got the weekly email from Little British Car Company and they're 
selling a pair of semi-sealed 7" round headlight with H4 LED bulbs that 
will work with positive or negative ground for about $90 (P/N 
171-LEDHL101). NFI. 
Cheers,
