Hiya Phil, glad to see you back mate.
I think EE/Halcyon lights are the mutts nutts but they are very expensive, if you contact Andy H (DalesDiver) he's just set my mate up with a wicked little Sartek 10w HID unbilical which is really sexy, we had it stood next to a Halcyon 10w HID and they were nearly exactly the same unit, infact I think the lighthead WAS the same, but the whole thing was less than half the price of the Halcyon
If you ring him he'll show you both lights side by side, I think you'll be impressed, you just need to add a webbing loop to slide it onto your rig and you're good to go... don't forget to get a goodman handle too.
All the best mate, hope to see you soon
Dave.
