I have read the couple of threads on spotlights, but feel there are more questions still unanswered.
I have been looking at the following Lights
Gamma Xenon HID Work Lamp http://www.narva.co.nz/EmergencyLighting_9.html
Predator 4000 Driving Lamps

Lightforce 240HID
http://www.lightforce.ie/index_main.php?p=240hid
These seem to be about the best that are being offered currently on the market that I can see. Price is going to be the deciding factor in the end, but daydreaming at this stage who can comment on the above?
