How about these ?
I can't tell if they'll fit. The product specs say dimensions are 10x4x2 inches. I think they're referring to the box.
Looks like they should be bright. They use Cree's XBD LEDs which kick ass. If you do get them, be very careful in handling as the 4 XBD's on the outside of the unit look to not have a lens. The built-in lens on the XBD's are some type of RTV-like substance which is easily damaged if touched aggressively.
We just made a pool light for a colleague using 24 XBDs with red, green, and blue LEDs. The original pool light had 2 white halogens with a rotating lens for other colors. By flicking the power on/off/on the rotating lens would stop with the desired color.
We went one step further and made an RS232 link between the LEDs and a control board outside the pool with a BLE processor. Now the LED light is controlled via smart phone app.
