I have a retro Lumicycle NiMH system with the standard 12w spot / 20w flood halogen lamps, but the battery is past its best so I now need a new system. I haven't got any experience of more modern lights, so I'd be grateful for any advice on how brightness in lumens is compared to watts. My impression is that my friend's 300 lumen Exposure helmet lamp is brighter than my 12w spot. Do you agree with that? Roughly speaking, how many lumens is equivalent to a 12w halogen spot?
Many thanks
