The new 15,000 lumen PLC-XF47 projector from Sanyo stakes claim to the "world's highest light output" title. And the 6500 lumen PLC-XP100L vies for the "brightest portable LCD projector" claim. Both of them feature 2000:1 contrast ratios and plenty of input slots as well. The PLC-XF47 focuses on specs like wireless HD streaming, 720p and 1080i video up to 100 feet away with less than a millisecond of latency and 1024 x 768 resolution. The PCL-XP100L has similar resolution but is a third of the cost of XF47. Expanding further, Sanyo also lines up the PDG-DXT10L which features 5200 lumens and a 2100:1 contrast ratio.

The PLC-XF47 will be out in October and will cost $30,000; The PCL-XP100L will be out in September for $10,000; The PDG-DXT10L is coming out in September for $7000.
