What about heat sinks?
I think there’s a misunderstanding about heat sinks.
Do the test at 80watts was with heat sinks,or they only require heat sinks at 80watts or above?
Also does the strips include heat sinks when purchased?

for sure with heatsink

What spectrum of LM301B is used that gives the charts and data?
What voltage are they ran at?
Do they come with heat sinks or do they only need heat sinks when driven at 80watts?

3500K plus Cree xpe 660nm, the voltage bin is AZ, we used the driver is 48B
