Q: What are the pads labelled '8S' to '1S' on the bottom of the board?

Z_itriix It is mainly used to distinguish 12345678S during production, and the function has no effect.

Q: What is the wavelength of these UV leds?

demandé par BG183915105 sur 2021-10-03 04:16:37

BruceMardle I haven't actually tested it, but the product description says 405 nanometres. That sounds right, comparing it with my 405nm laser pointer. The light looks pretty dim but it's not entirely invisible. (It makes a lot of things fluoresce blue, which can be confusing!)

Q: What size holes do these cut?

demandé par BruceMardle sur 2019-06-03 11:32:17

donaldsneffe 4,6 and 8 mm and 3 mm punch, but 6 mm does not cut in mine, it is flat at the end. All in all super poor quality.

BruceMardle The line laser and the cross laser are 2 separate products (though the cross laser is out of stock as I write this).

BruceMardle The 5mW refers to the light output, not the electrical input. Anywhere between 3V and 6V input should work. (I'm not sure if the output is higher at higher input voltages. I don't have mine with me to test.)
