I'd be interested to know how they can justify selling components at such silly prices.
1 white LED, only £1.84.http://www.maplin.co.uk/5mm-superbright-white-led-45936I can buy 5 sticky LEDs with batteries included from PoundLand for £1 and it's not like buying from Maplin brings better quality. I'm better off with PoundLand, at Maplin there's no data sheet, no brand name and no customer support but PoundLand are cheaper and they don't pretend to know what they're talking about.
Maybe they should stop selling single LEDs? I'd rather be forced to buy 5 branded white LEDs for £2 even thought it's expensive, I'd pay the extra for convenience and having a propper data sheet.
Again look at the quality of some of the responses to questions.
http://www.maplin.co.uk/5mm-superbright-white-led-45936Q) Does this 5mm Superbright LED need a resistor or can it be run directly from a 3V source?
A) they need a 3.5v source to work.
No you idiot, you need more than 3.5V and a resistor.
Q) will this led run from a 12v battery or is the max voltage 3.6v??
A) The maximum voltage that this can cope with is a 3.6V DCYou moron, the LEDs can run from 12V if a suitable resistor is used and if you weren't some retard with a D or below in physics you'd be able to calculate the correct value using Ohm's law.
Q) With continuous use, what would the expected life be of this type of LED
A) 1000+ hoursI'd never buy an LED which only lasts 1000 hours, even the cheapest nastiest LED should last ten times as long as that.
Q) Can i run these LED's off a button cell and if so which one? If I can, can i run 2 LED's off the one button cell or will two have to be used? Thanks
A) No sorry this product does not support that.Maybe if you'd suggested using three button cells in series, you might have made a sale.
