Oh come one now I run a 1,750 lumen bar light and a 1,000 lumen helmet light and on high they are only warm while moving. Holding them in my hand for any length of time though while standing still is another story. They are for trail use, but I usually bring both lights whenever I go night riding. 9 out of every 10 rides I do I never come across another person on the trail or MUP as it is usually after midnight so it is not an issue. I always dim way down when I see someone coming though. As far as rear blinkies I have a couple superflashes that I usually turn off on MUP, MUTs just to save batteries.
