Just a word of advice, if you’re “forgetful” and might leave on the light unattended, a) try not to use the highest modes, and b) never ever ever set it on anything lens-down. Not unless you want the light to cook itself (a), and not unless you want to melt/burn whatever’s underneath the light (b).
Turn the light on high and just put it against the back of your hand for a few seconds, and you’ll feel how hot the rays get. Some lights (eg, the MT09R) can actually set things on fire.
