Luga Horticulture cobs and strips

Luga spectrum looks like nearly the same as from the citi horticulture cobs....the stripes are described with 2,4 μmol/J efficiency at 700ma/33.4V..... do they have other "bloom" spectrum.. "The slightly pink-coloured full spectrum light"? .....because the shown cob looks really pink to me

The pinkish 2600°k HB strip looks interesting for flowering with it's increased far-red output and red peak @650nm.
Any info about strips prices?

I sent them an email earlier asking where can they be purchased, in small amounts, for testing purposes. ;)

Ah, great!
COB's and stripes seem to have the same data because the strip is just a long COB and 2.4μmol/J is not bad at all. 2.6μMol/J should be possible at 350mA. But if they are just as expensive as the COB's, huh nope! 25€ or 30$ is too much for such an 280mm strip.

I checked the SPD on the citizens and they have a lower red peak it seems.

If you read the datasheet, the bloom COB's are optimized for max. photosyntesis. Seems they have not heard of the emerson effect and how useful a small amount far-red can be. But to be fair, they are focused on greenhouses as supplemental lights, not for our purposes.
The pinkish spectrum of the veg COB's looks somewhat similar to the Luxeon SMD3014 Fresh-Focus diodes just with a bit more green.
