The Tek Light fluorescent grow lights are very efficient systems. Each bulb produces 5000 lumens of light and draws only 54 watts, 92 lumens per watt! A typical F40 cool white lamp is only 31 lumens per watt. The lamps have a very low heat factor so you can hang them closer to the plants. Having the light closer to the plants will utilize more of the available light. The reflector is made from 95% reflective material so very little light is lost. The ballasts are solid state electronic with no copper windings and are very quite with almost no heat. The ballasts are positioned away from the lamps for longer life. Includes backlit on/off switch. Comes with 4 eye bolts and 2 "V" hooks to hang the fixture. The T5 lamps come in two colors, warm and cool. The warm bulbs are 3000 Kelvin and the cool bulbs are 6500 Kelvin. The warm bulbs work well for starting seeds and for flowering plants and the cool bulbs work well for plants with a lot of foliage. Tek Light T5 4 Ft - 8 Lamp - 40,000 Lumens, Measures 48" x 19" x 2.5".
