These are probably UV Leds.

Find some kitchen scales and weight 10

Use the 10 to weigh out 100. No more counting

If they are UV LED's (test by shining on white Tshirt or Washing powder) How much to ship in a jiffy bag to the UK ?

Don't confuse the 'merican...... we just call them padded envelopes over here.

(The only "Jiffy" we know in the US is peanut butter)

doubt if they will live long at 6 volts??

purple means red + blue usually. maybe the red part was from heating??

dunno... leds don't usually shift color with output...

jim5763 · 21st February 2010, 12:39 AM

i didnt leave them connected at 6 volts very long,they were alot brighter @ 6v probably just brighter purple.

Some UV Leds appear purple, there are some lighter ones which are pale blue/purple colour. Both types will cause fluorescence in white objects. copy paper is a good test

See image of UV Leds across some paper.

PM me with details of costs
