Buying the LED strip

I’ve just had a query about sourcing 670nm LED strip. I have found it hard to get 670nm of late, so in recent Eliza-making, I’ve resorted to any old red LED strip.

This is how to buy the best “any old red LED strip”:

  1. You can’t buy it at a regular shop. You can only get it online.
  2. main thing is to look for the one with the darkest red colour. They are available on eBay and are not at all expensive.
  3. Make sure that it is 12v (12 volts). Most LED strips are 12v, but I’ve recently seen a few that aren’t.
  4. While 670nm is currently regarded as the bees knees, other wavelengths are also effective, including down to 630nm which is is getting towards an orange colour.

Search term: red led strip 5m 12v

 

Don’t get hung up on finding exactly 670nm LED strip. Just find the darkest red LED strip you can get, and use that.
