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”:
- You can’t buy it at a regular shop. You can only get it online.
- main thing is to look for the one with the darkest red colour. They are available on eBay and are not at all expensive.
- Make sure that it is 12v (12 volts). Most LED strips are 12v, but I’ve recently seen a few that aren’t.
- 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.
