WOW! I just bought 10 Bysen SK 114 D strip lights, straight from Sophie at Bysen. The SK 114 D is the strip version of the Chloro BA2 and it has 8 COB's ......4 vege & 4 Flw/Acc. Growing lettuce with the vege spectrum......forget about using the Flw/Acc spectrum. Really happy with it's performance - it just blew away my Illumitex ES 2's and 9 other LED's we used for testing purposes. We had actually committed to the Bysen SK114 and were about to purchase 100 more when I got an email from Geyapex asking me to test their new COB. I agreed if they would send it free as we had already committed to Bysen.......they did.......and......their LUMA B4 blew away the SK 114 D big time. Still can't believe it..... I can't deal with the fans though.....so they offered to redesign the light without fans. I've only seen pictures of the new light so far.......wow!......anyone wanting information or pics I will forward them to you......remember it's for lettuce. They use a CREE COB or the Citizen version of it. Use PayPal.......no doubt about that.
