That's right Poxon,some people still get the Cluson "Lazer" light what still has got a plastic reflector hence going to a 100 watt bulb through heat it would damage the reflector,but with the Cluson" Blazer" light because it has a metal reflector it can handle the heat etc and if you find the 100 watt bulb too strong for your purposes you can drop down to a 75 watt or even 50 watt bulb no problem.Then of course theres the vertical/horizontal filament which throw different beams ,but sticking to my question i have emailed Light Force International.
