These are 30mmx400mm (approximately 1.2 inch x 16 inches) 96 Diode Strips using the Samsung lm561c top bin diodes. For the size, number of diodes, efficiency, versatility, and power capability, you won't find a better deal than these strips.
This listing is for 8 of the 2700K strips and 4 of the 6500k strips. The 2700 is recommended for the flowering stage.The 6500 is recommended for the vegetative stage. If you mix these together 2 of the 2700 for every 1 of the 6500, you end up with a great mix reaching more of the red and blue spectrum than you can with any single color. They actually work amazing with a MeanWell HLG Driver with a constant current of 1400 and are highly efficient at this power, but if you want a little more power, a 1750mA works great, too.
For example, a Meanwell HLG-185H-C1400B powers three to six of these strips nicely. With 12 of these, they would work perfectly with either two of the Mean Well HLG-240H-C1750B with series wiring and give you 550w(at the wall). This will give you one hell of a light. There are many other configurations that work(too many for me to list), but plenty of resources out there to learn a little about wiring them different ways to help you decide which way you wanna set yours up. If you don't know any, just ask and I can point you to one or two great ones or answer any questions you may have.
If you look around, you can even find ways to set them up on regular old full size cookie sheets.
