QB 288 V2

Horticulture QB 288 V2 are now made by Samsung using the latest LM301B LED. Currently QB 288 V2 is available in 3000K and 4000K Spectrum. For a Comparion of QB 288 V1 and QB 288 V2 see our next article HLG 550 V2 vs HLG 550 V1

The Original QB 288 was launched in November 2016 using LM 561C with A1 voltage and S5 flux bin. In first quarter of 2017, QB 288 was upgraded to AZ voltage bin and S6 flux bin. In May 2018 we launched QB 288 V2, which uses Latest Samsung LM301B LED with highest flux bin and lowest Voltage bin. Currently QB 288V2 is the most powerful and efficient High power Horticulture light engine available.

I wish you would offer offer Q -boards with 12, 24 and 48v nominal voltage options for battery based systems. Coupling solar/ wind energy with high efficient LED is of the greatest efficiency and makes great sense. Utilizing high efficient DC solar collectors and wind turbines with Maximize Power Point Tracking (MPPT) technologies and DC voltage controllers could Directly power led lighting, without the use of a specific led driver. Also one could enhance growing conditions utilizing both alternative energy and LED lighting simultaneously. in this application a green house for example during periods of low solar radiation could efficiently extend growing conditions during periods of low solar seasons.

Hey how’s it going guys? I was wondering what’s the highest I could run my 320 fixtures. I noticed when I turned the dial it reached 360 and it could have gone higher maybe. Is it possible to burn out thediodes if I turn it to the max? Thanks for all your help . I’m running two in a 5×5 space
