Then they should be fine. Still don't really understand why the k1 and k2? there is aso no legenda to explain this number, the rest is al labeled. With cheaper prices and free shipping to my location sounds like a sweet deal. They are also offering 5* 1212 for 44,88 euro.

its just internal codes
AL7K3 = 70 cri in all models
M2K1 = 80 cri in all models
H5K2 = "normal" 90 cri ("On BBL")
H6K2 = "below BBL" 90 CRI

the H6K2 has a different chromaticity and approximately 10% less lumens per watt. per datasheet the spectrums look identical to me. i dont understand if theres any advantage for us to this chip, and so i dont stock it because of the lower output. all my 90 cris are H5K2s

Do you know much about this chip @CobKits?
CLU048-1212C4-403M2K1
its just a 4000k 80 cri, same as i stock. good universal color if you want one chip for both veg+flower. i cant match his 180 pc price (well under my cost), but i can match that 5 pc price on those colors

what you you guys think about $50/free US shipping for 5 of the 80 cri 3000k and 4000k chips? or just call it $10 chips free shipping for 5+ on those colors?

Everybody probably for free shipping and lower prices, but i didn't want to bring your prices down or something just trying to share some back to the community as i learned a lot also from your posts.

markets are markets, competition is good for everybody. euro growers would be smart to take advantage of that pricing, and hopefully i can take care of US growers as well. even if i make next to nothing on $10 chips, site traffic is site traffic and doesnt hurt in the long run. people always need other stuff

Can anyone confirm that correct mounting holes spacing for CLU04X & CLU05X is 32.24 mm and 45.26 mm respectively? I'd hate to have it drilled wrong.
