Yep. Nicely timed offer from Screwfix there for you. (y)
I've just seen the Screwfix Diall LED light offer with free tripod posted by idontflycathay which looks better than mine! I'm binning this and going for that one!!
Glad I didn't go for the 800W ones then (shock)
Or melt your hat to your head! True story...
Depending on the setup of the lamp. It should be fairly easy to use LED lamps inside these units when the halogen tube goes.
