I'm sure I've read a stock stator can't be wound to make huge amounts of wattage, maybe squeeze an extra15-25w max.
Also remember you lose wattage through a dc current
Go with some led lights, I've just fitted some 6w gu10 bulbs in my kitchen and it's like having floodlights on!!
Don't some of the trailtechs use a gu10 or mr16 type bulb??
