hi Guys,
Topic please.
Moderation.

 

It was the TS that raised the question of the existence a website. It is arguably "on topic" for understanding why or why not it might be the case. If it is not on-topic, then maybe the TS would like to have you delete the posts. It is his thread after all.

 

The TS asked Danko a question regarding, did he have a website, Danko replied to the TS's question.

You then effectively hi-jacked the thread, by posting queries regarding website costs, etc, which is not the TS's topic.

I considered a gentle reminder to keep on topic would be the right action.
The matter is Closed.

If the LEDs in that manufactured are in series then the voltages will add and you need more than 3.2 volts. But the very first thing is to find what voltage is specified for the strip.
If no information is available then you can use a DC power supply and a higher resistance series resistor for the while strip, and discover what the forward voltage at the terminals should be.

 

I can’t add resistor to each LED as I’m doing for off the shelf led strips and (long story!) can’t just replace with another type.

This is why it's important to link to the exact product. Many LED strips are designed to work at a set voltage and the strips include current limiting resistors. This is but a single example. The example happens to be daylight white. I also see strips for 12 volt power using RGB LEDs. So need to know exactly what you have or exactly what you are replacing. As I mentioned "strips" normally include current limiting resistors and can be cut to desired length.

You promised to send this information back in post #13… What happened?

 

In post #5 suddenly there is a change to ready-made "LED strips" and in post #6 a request for more information.

Currently there are many different LED types and quite a few of those types run at far more than 20 milliamps. Thus it seems that the TS must either provide some additional information or else do a bit of experimenting to determine the actual current and voltage requirements.
Thus there is no reason to continue providing random guesses until the TS provides more information.
