For the price of a decent car the JVC 4500 probably pumps out the brightest picture at full P3. My guess is the JVC 3,000 and then 2,000 are next at around 1,800 lumens. If you don't have a fully light controlled room meaning not only window light but also dark carpet, walls and ceiling then I wouldn't pay the HEFTY premium for these machines. Where they excel, in a big way, is in very specific environments. If they aren't in their natural habitat then what you've done is bought the best of the best winter coat money can buy to take on your tropical vacation and you've paid a mighty premium for it.
