sure about the eu warehouse? every order so far i or a friend did via digikey came from the states (5 orders so far), good thing is customs and shipping is already priced in, you only need to pay VAT on your orders so i don't really mind where they are shipping from, it's usually faster than ordering from tme, where i usually get my meanwells from, and they sit in poland

I have Sammy strips on order.
I thought they'd be coming from EU warehouse but they appear to be coming from
Thief River Falls, MN, USA....?.
As long as they arrive, that's the main thing :lol:

Q-series don't need thermal grease. Simply screw them on an alu sheet or alu strips. You can also use them without heatsinks because of their low wattage. Other 2ft. strips like F-series run with 25w and reach 65°C with no heat sink. This means you could drive Q-series even at max. current(900mA/~21w) without any type of heat sink.

It seems like PLC and cutter.com nichia strips are out of stock STILL lol... Would the Q strip be my next option for maximizing efficiency of light (uMol) to order TODAY lol my design is like this Screenshot_20190409-055036.jpg

You can use Samsung Q- or H-influx Series. They both use LM301b!
But H-influx has a lot more diodes compared to Q-series and you can get them with double row layout. So if you drive them with less current you can get the same efficiency like from Q-series but with less strips.
The most efficient is L06 cause of his highest diode density. A 2ft L06 strip has 88 diodes, a 2ft Q-series strip only 40.
