Universal UV lamp
The Universal UV grow lamps (plant stressing) are shipping. These are based on our A10 prototype that has been used by a number of horticulturalists. They also make exceptional wood aging lamps, as they are multi-phosphor and have around 10% total UVB and no visible light phosphors. Of course, they still produce plenty of visible light due to how mercury bounces around in there, but the phosphors we use were selected to be the highest energy with the least waste. Most people are backing these 6 or so feet from their plants, and covering 4 to 8 plants with each bulb, making them insanely affordable. We have them as individual bulbs or kits, you can check them out here.
