The differences between graphs that people find so suspicious can easily be explained by the different units used up the left side of them. Most notable is that while some use a straightforward unit measure of some type, the other uses a 'percentage of total' measure- which not only doesn't arguably quantify anything, but also distorts the graph slightly. The graphs aren't lying but since several different types are in use, one has to be careful to only compare apples to apples.
I this game, it appears that horsepower is currently king over finesse; bigger bulbs provide more value than smaller ones with better spectrum. I hear plasma may make the reverse argument, and that interests me. At least it will once the price comes down!
