Description: This is a very simple, clear infrared LED. These devices operate between 940-950nm and work well for generic IR systems including remote control and touch-less object sensing. Pair them with any of our IR receivers (see Related Items below). 1.5VDC forward voltage and 50mA max forward current.

Customer Comments

  • These are extremely bright!…using 1 of them for a TV-turn off'er and i can turn TV’s off from 400ft plus!

  • Just a note: On the front page they listed Multi-Touch tables as a possible use for this IR LED. You actually would not want to use this for that.
    The 940-950nm is too long of a wavelength to be picked up well by IR cameras. Most IR cameras are most sensitive to the 850nm (or “almost red”) area.
    But this is what you would want for a remote control.

  • What is the Manufacturer Part Number? Its not on the datasheet.

  • I would like to know how far the light of this LED can reach to IR-Receiver. If I can find things like ‘Light intensity’, can I calculate the distance?

  • I think using these to build an ‘invisible light’ flashlight with my daughter would be a really fun evening science project. Anyone know if these are a viable way to illuminate a dark scene viewed through an iPhone Camera?

    • You might need a few to get any appreciable level of illumination at further distances. Compare it if you will to dedicated security cameras. Their IR illuminators are generally a whole array of IR LEDs. Keep the above comment by dr.light in mind, though - 850nm does work better with cameras. SFE (still) doesn’t have those back in stock, though :)

    couldnt you use a ps3 eye, OEM lense modded, with the correct bandpass filter installed?
    at any rate - 850 does perform a lot better - ive tested a number of ranges of IR over the past mos and ive settled on using 850nm LEDS and had some success with 780nm lasers…the 850 were out of stock from a supplier, and almost $30.00 more expensive!

You asked me today in three different emails for a review, and I haven’t even taken these out of the bag. Way overkill!

Perfect

Perfect for my project and a very reasonable price. Good quality.
