ghostoker theres loads of people who just get it into there heads that anything under 400watt just aint worth the bother,but most those people have large rooms here there runnin 4 & 6 400 watt lamps at the same time,dont risk the fire hazard bro,go with the 250 watt.
That was quiete a story u sent about the chap burnin his house down SJ,either too much HEAT or he wasnt the best at electrical DIY!either way you shouldnt risk the chance of fire when you put other folks lives @ risk
