I have had a Ikelite PCa Halogen for quite a while and have been quite pleased with it but the 6xAA's only seem to last for 2 dives and the light is a bit yellowish. I was considering buying the PCa LED since it produces whiter light and batteries last longer. Is this type as bright for as long as the halogen? Then i heard that next month Ikelite is putting out the Gamma (also LED) but uses 2xCR123 lithium batteries and is same lumens and even longer burn time. Maybe i should wait for that? These small cheap torches are enough for me but i would like one that stays bright for longer before dropping off rather than one that gradually drops off in brightness from the start. Also, do the LEDs shine as 'far(?)' as the halogen?
