New projector lamp - hybrid laser and LED light source

Looks like this is the start of a new generation of video projectors - the lamp technology looks very interesting :

• Longer light source life Use of the laser and LED hybrid light source increases the light source life to approximately 20,000 hours — nearly 10 times that of Casio’s conventional products (XJ-S58, etc.) with a high-pressure mercury lamp resulting in lower maintenance requirements and operating costs. Moreover, brightness deteriorates more slowly than with mercury lamps, so clear image quality can be maintained for a long time.
• Laser and LED hybrid light source that enables mercury-free, high-brightness projection High-brightness projection is achieved without a high-pressure mercury lamp by using blue light emitted by a blue laser, green light converted from blue laser light with a phosphor, and light emitted by a high-lumen red LED through a DLP® chip onto the screen

What sort of power would you need to get 2500 lumens? Blue is only like 70lm/W isn't it? Multiwatt blue (5 figures?) probably costs too much more than a regular mercury bulb (2-3 figures?) to be worth it.

Sorry, missed that one!
