Thanks manxbuggy. The driver in the monster light is back to the dicky one that over heats on high and medium in about ten minutes. You can wack either of the Thrunites on high and forget about them. Things like moulded rubbers around lens, drivers that work, etc etc just make these quality items that work terrifically. I'm not sure if you have seen it but theres another thread with these night shots and a heap of others I should of dedicated to you and your brother for the inspiration. I'm a bit slow at the best of times.
