  • I've sent you an email through the spectradesignlab.com. Is paying with cash an option?
    Hi man, I am checking your lights and I am interested in spectra cob4. I am planning a small grow for about 60x60 at first and then maybe upgrade to larger tent. What do you think ?? PSUAGRO told me that also a discount for riu members can be done...can you please give more details (something more specific) ? :) What kind of payments are available (visa, mastercards, paypal..)? Thanks in advance.

    for 60x60, COB4 it's perfect.
    we extend the discount to all,on site the price are lowered and the best we can do.Paypal it's okay.

    Currently COB4 seems to be out of stock..do you have any estimation when it will be available again?

    In your space it's enough about 250W with 8 cob, and a COB4 system itt's dimmable to 125W can keep plants even to 3 inches from it
    because it remains almost cold.Regardless of the choice you make, will highly recommend this spatial configuration with at least 6, but perfect 8 COB, however, similar to COB4 for alignment and distances, calculated on the correct overlapping of cones of light.

    Thanks for this information. Two COB4 sounds like a great situation, but ultimately it will come down to price vs the cost if I build them myself. Can you email me a quote including shipping to CA, USA at [email protected]?
    Is this a pm or public? Wanna pm you

    Those are sharp lights. Is the knob a dimmer? What CREEs are you using & are they top-bin? I saw a lense option. Without the lense are the cobs protected by a primary lense? Are the Posted PPFD readings w/o the lens & 12"? Is it modular & can I put different K-Temp COBs in? Can you offer a PPFD grid @ 18? How much $) If I bought one & liked it, I would need many for myself & my large-scale grower friend.

    Hi, the knob is a dimmer, we use selection of Top BIN CREE AB and AD.
    Any COB is naturally protected by primary lense part of the same cob.
    In normaly climate controlled environment there are no problem.
    Yes is modular and you can put different CREE CXA3070 K-temp you want, or upgrade with different Bin.
    For data or reading I need some days to make it.
    Are you in UE?
