Keeppower Panasonic batteries have arrived!! (two changes of suppliers, ‘lost shipments’ and paypal disputes later :D) If I had any idea it would have taken that long…anyway, I knocked up a basic website over the weekend because keeping track of everyone’s emails over hotmail was getting very confusing. (you may also notice I haven’t been to design school) mtblights.co.uk. I was really happy with runtimes. I rigged up a watercooled X2 in the kitchen sink and left it running. On full power it lasts for 3 hours 15mins, the power indicator will flash at about 15-20 mins left of full beam. The light will then continue for 1.5+ hours on a lower beam. It would have kept going for longer but I had to go to bed.
All in all very happy with the result. I’m going to test medium when I get time over the next few days.
Hope the info helps, Ollie
