I have a 50mm ARLEC 200 lumen rechargeable torch that charges from a sub port.
I think it's brilliant.
Good light and throws it quite some distance.
Lasts quite a while too.....about $25.00
I recently saw a couple more ARLEC torches in Bunnings.
Range fro $35.00 to over $100.00
400 lumen up to 1000 lumen.
Haven't bought one yet, but if they are half as good as the little one, it will be a good buy.
I also have a 100,000 lumen Firestorm, I bought in China years ago.
Don't know it's true output, the Chinese tent to exaggerate a little.
BUT that thing can outshine any Hella halogen light there is.
I can light up an object about 1klm away.
Have not seen one anywhere else since, AND GETS QUITE HOT AFTER ABOUT 1/2 HOUR.
The batteries are rechargeable but it takes a while, it lasts about an hour on full volume or 5 hours on low.
