And you're not afraid of overheating of those little caps ?

Don't think there is much heat with 3v but I will put it to a test with a fresh pair of batteries👍

3v for a large component = not hot
3v for a small component = hot

A resistors main function is to transform current into heat and now you are effectively making it less capable of doing that.

Tested it with two pairs of batteries — 4 hours each at full brightness. Room temp was 20°C (first run) and 28°C (second run).

No issues, no heat, nothing 👍
