A Decision, maybe?

After much agonising I think the old BLTs will be out the window. I had them connected up to a 6V battery charger and they were great. They're 10W and 2W bulbs. Electron are making a light that is based on the lighter NiMH battery with a 10W/5W combination and it's about £50 - That should suit me to the ground. It's not worth me trying to cobble together a new power supply for the BLTs - I'd end up saving myself £10-20. If I can get a pic of BLTs lit up I will.
