    Default Laser diode lightbulbs?

    Interesting story.

    remember the cold war era when they had the 20 thousand dollar hammer and the 30 thousand dollar toilet seat?
    I wonder how much this is going to cost taxpayers -
    Will there be three phase!!!!

    Why is it always presumed that people prefer warm white?

    When I buy energy saving bulbs I always buy the cold white as the icy white is a lot more sexy that than horrid yellow glow.

    Maybe the cost of yellow diodes means we'll see cold white 1st.

    I doubt these 'light bulb' modules will be driven RGB.

    Since you don't need (or even want) a collimated beam if you want to replace a light source, it's a lot more cost effective to use a fat beam 445 and a fluorescent layer on the outside of your bulb.
