different manufacturer. Cree were big a couple of years ago, now Seoul seems to have the lead in power consumption verses luminosity. The P4 is what is in the Exposure joystick and is nominally 240 lumen, the P7 has a claimed output of 900 lumen.
Probably best getting one with a standard battery. They did have a few that uses a aa battery holder though not necessarily a p7.
The last thing I ordered from dealextreme took about a week to arrive.
