OK, Bluebottle, here's the details.
I tried investigating earlier but was getting results which made no sense - a voltage which would be too low to light them but a current which would blow them sky-high. I think the problem was that my brain hadn't warmed-up to full emission.
The LEDS are drawing 23mA at 3.6V. As they came off e-Bay I don't know their full spec but these figures seem reasonable and they can be on for hours at a time without blowing.
My personal attitude is to not worry about things too much. I regard my self as an amateur practical radio mechanic who repairs things rather than a scientific radio engineer doing restoration work. No disrespect to those who work to other standards; I'm pointing this out because I often can't explain exactly how or why I've done something. I tend to arrive at solutions by experiment and just take the flashes and bangs as part of the process.
Cheers
