    The taillight conversion thing.

    Muddling about on ebay I have pretty much just fallen off my chair. I think I have found a ready made heat sink.

    60 X 120mm Heat Sink for 1W 3W 5W 10W 20W RGB White/Warm White LED | eBay

    It will require some machining and maybe a small fan - but I am enthused.

    It will allow all sorts of LED options. No really! - I am pumped.

    Ordering a pack of them now. The LEDs are easy compared to this find.

    The LEDs I hope to use should pump out almost 1200lumens (3*400) on Brake. That is the raw value. We shall see.
    May change depending on the electro-meisters feedback on PWM for the tail(running) option.

    Now I just have to open the taillight up - thanks to @laraza I have a spare.

    So!. His electrics-ness confirms PWM should be a suitable solution. Will order LEDS after work today.

    1200 raw would be about like a fair torch real value, no?
    Perhaps 800 or so depending on atmospheric conditions?
    Difficult to put into real world perspective without a good light meter test.

    More than atmospherics it depends on how much light the lens gobbles. But think on this - a 21W Tungsten bulb is about 400 new and spec'd at 160-ish - but generally agreed to be about 200-250lm. The 5W bit naturally MUCH lower. tbh I think I will end up having to tame it a bit.

    Amigo,
    You need to get yourself a light meter so you can do some testing that gives us real world values.
    There are inexpensive incident meters out there good for your purposes.
    Look up the Extech EX30

    If the heat sink is in the enclosure is there enough cooling air volume?

    Sorry Amigo,
    I have used several apps regarding motion and liight.
    None I have seen compare regarding reasonable accuracy.
    Give me a link and I shall check it out.
