What are the benefits of led lights over traditional MH/HPS lights?
●.Lower energy consumption
●.Longer service life; LED bulbs can last up to 100,000 hours
●.Durability; LED bulbs are resistant to thermal, vibrating shocks and turn on instantly from -40°C to 185°C, making them ideal for applications subject to frequent on-off cycling
●.Flexibility; LEDs allow for directional distribution of light
●.No infrared or ultraviolet radiation – UV light attracts bugs
●.No toxic chemicals; LEDs contain no mercury and do not require ballasts, which are often manufactured with PCBs
●.Very low heat generation; LEDs are can reduce climate control costs and are especially suited for cold storage facilities
●.No frequency interference; no ballast to interfere with radio and television signals
●.Wide range of color; LEDs can be manufactured to produce all colors of the spectrum without filters as well as white light in a variety of color temperatures
