5mm UV LEDs for sale. I have immediate stocks.
You won't find this cheaper anywhere. These are new and quality stuffs, not pulls and not old stocks.
Hasn't got a chance to try these LEDs on UV paints/markers, but tried them on a currency note (see below). The UV light saturated my digicam so much that the fluorescent paint on the note can't be captured properly unless the LED is shoned off-centered.
Some specs:
Peak Wavelength (typical): 395nm
Typical forward voltage drop: 3.8v
Typical forward current: 20 - 30mA
Datasheet here
Prices:
USD$1.20 per piece
USDS$5.50 for 5 pieces
USD$10 for 10 pieces
USD$20 for 25 pieces
I can only accept payment thru paypal. Add USD$5 for registered airmail shipping from Singapore.
All UV Leds will be doubly packed in anti static bag and shipping foam to prevent damage.
Postage for registered mailing will be waived for purchases above USD$50
More attractive pricing awaits for larger orders. PM me.

The UV led shown in the photo above was powered with 15mA, half of its maximum rating.[/url]
