It is true that you get what you pay for. The $250.00 lights are the brightest lights available and are used in most construction equipment( cat dozers, power shovels, etc) They are very bright, but for average Joe; just buy the biggest watt lights for the money. I have 35 watt, rubber housed lights now, 2 forward and two rear mounted. I do some night work and they are not bright enough. I just was given a set of driving lights off of a jeep; I think they are 55 watts; I temporarly hooked one up to see if I noticed a difference; it was amazing how much more light was put out by a 55 watt halagen bulb.
