    Lights on a Chrono for Indoor.

    2 x 5 LED bar lights off the bay. Run on AAA batteries. About a fiver including batteries.
    Tape them on the underside of the diffusers. Ensure your shots through the centre section & about 4" above the detectors.

    Got an LMBR R2A delivered this morning to replace my Chrony. Absolutely brilliant, no worries with extra lighting.

    Be careful - some LED's use PWM - pulse width modulation which makes them flash imperceptibly to the eye - and this might affect any chrono reading. They do this to save energy, or lower the light output. One simple way to check this is to point your smartphone at the light in slow-mo mode or other high framerate video mode - if you see pulsing, it could well be using PWM.
