Your going to have to stay with the HID’s but a combination of both will keep the amount of HID lighting needed way down. This means less of a heat footprint, lower electric bills and more production per square meter.

The shear amount of light HID fixtures provide is staggering. But so is the energy consumption and especially the heat. Due to the directional characteristics of traditional metal halides, the bulb produces mass amounts of wasted light from the top and sides of the lens. Advances in modern LED lighting have created new and exciting opportunities for horticulture. For example a LED light dissipating 60 watts of total power would need to be replaced by a metal halide bulb dissipating 400 watts of total power. The LED fixture produces 18,000 Lumens while consuming a paltry 213W….thats a 54% reduction in operating costs. Besides LED lighting is 70% cooler than HID lighting. LED lights generate significantly less heat when compared to the metal halide bulb. Not only do the LEDs generate less heat, but they also dissipate their thermal energy back into the mounting fixture. All HID bulbs dissipate heat from the front of the bulb and down into the plants. This can make thermal management a challenge, as we all have experienced
