We’re testing these dirt cheap LED’s with a decent IP rated meanwell driver
That looks really interesting - are they 7cm long?
Are you testing different colours?
7cm seems about right.
At the moment we’re just using the ‘warm white’ ones.
I suspect the red ones are just white LED’s with a red filter, but it’s possible they are actually red LED.
Might be worth getting some to have a look.
I’m planning to test them under a PAR meter to get an idea of their Par/watt.
