Power Consumption:LED Grow Lights vs. HPS light
LED Grow Lights are well-known for consuming lesselectricity than HPS (high pressure sodium) lights, but thestatistics can be confusing.Some sources claim that LED lights use 90 per cent less powerthan HPS lights,while others quote a more modest, thoughsubstantial savings of 50 per cent. Every indoor garden isunique and will differ somewhat in the power needed by thegrow lights and the energy used to cool and ventilate the area.Using LED Grow Lights improves the energy efficiency ofyour grow in several ways.
LED Grow Lights need less electricity to run than HPS lights and havea long er bulb life. Over time, HPS bulbs lose efficiency, becoming dimmer while still consuming the same amount or even more power. Over the course of an HPS bulb’s lifetime, the actual operating cost of the bulb increases sharply, whereas an LED bulb consumes only a little more power near the end of its life. After the initial set-up cost, power is the biggest expense of indoor gardening, so theefficiency of your grow bulbs makes a big impact on the overall costof your garden.
HPS lights put off more heat than LED Grow Lights, which often comewith integrated heat sinks. All that heat exhaust from the HPS lights requires ventilation, adding to your indoor garden costs. LED Grow Lights put out less than half the heat exhaust of HPS lights, saving you a tidy sum in ventilation expenses. A room full of HPS grow bulbs will require quite a bit more cooling than an indoor garden equippedwith LED bulbs. Both gardens will require some air conditioning, butyou will need to run the air conditioning system about twice as muchfor HPS grow lights as when using LED Grow Lights.
When you calculate the energy savings of running LED Grow Lightsversus HPS lights, LED bulbs come out the clear winner. Thanks to the longer lifespan of LED bulbs and the fact that they do not lose much efficiency as they age, your savings only increase over time. Besides LED bulbs’ lower energy consumption, they also require less air conditioning and ventilation than HPS lights, raising the overall energy efficiency of yourindoor garden. Though the specific statistics will vary between indoorgardens, you can expect LED Grow Lights to be significantly more costeffective in the long run than HPS grow bulbs.
