best red LEDs for home made bicycle lighting ??

[brugnospamsia]

Dear group

I've just made myself a 9 watt fluorescent front light for my bike from a
decapitated mains CFL and a camping light invertor. It replaces a 12 volt 21
watt "reversing light" (early days yet - it remains to be seen how it'll
cope with cold, damp and vibration).
It's designed to be seen by others rather than to see by. (I plan to add a
20 or 50 watt dichroic spot for doggy doodo and broken glass avoidance.)

While I remain unconvinced about LEDs for the front light, I now have a
notion to replace the effective but inefficient12/21 tail-light with LEDs,
(if only someone would make a 9 watt "D" CFL with red phosphor ! ) ....but
I'm overwhelmed by the vast range of superbright red LEDs on the market.

I wonder if anyone here has worked out the most cost-effective device
specification for this purpose - would a shed-load of lower intensity
devices be more effective than a few ultra-bright narrow angle ones for
instance?

Hi,

I have meailed you (hopefully) via your website regarding your LED
dilemma.
Basically I am in the process of making and converting Motorcylcl tail
lamps to LED operation and as such I have numerous PCB created that
contain from 15 - nearly 100 RED leds. The smaller PCB's can easily
accomodate while LED's instead so one of these could be placed into
your smaller original front lamp.
Let me know if you are interested. I am not trying to creat a huge
commercial enterprise, just doing this as a hobby and to cover my
costs and make a couple of quid as well.

Regards,

Martin
