Will LED grow lights is hot as HID grow lights?

Led plant grow lights are increasingly favored by home and commercial marijuana growers. Compared with the traditional high intensity discharge (HID grow lights) lamp, the best LED grow light has many advantages. But one of the advantages is that the LED grow lights with low heat output, High efficient and cool in operation.

In fact, any electric appliance will produce heat, so all types of grow light bulbs will produce heat. However, compared with other types of grow light bulbs, LED grow light bulbs consume much less energy, so they produce much less heat. In general, LED grow lights produce less heat, making them a reliable choice for mission lighting or any area that may produce heat problems.

To put it simply, the LED grow light is less than 40% of the growth area of the HID lamp with the same wattage.

Nevertheless, all led grow light system manufacturers recommend hanging LED grow lights at a certain distance above cannabis plants for a reason.

First, even LED grow light can only convert about 80% of electrical energy into light. That is to say, only about 80% of the light leaves the grow lamp. The rest of the energy becomes heat.

The radiator in the LED grow lamp guides most of the heat into plants and is far away from plants. The rest spread out and won’t bring any real problems to your plant. Nevertheless, high temperature will still affect the performance and life of diodes

But in addition to radiators, the best way is to eliminate moving parts (and additional power consumption) by simply using good materials and special design.

This is the way that LED grow lights generate heat, which is more relevant to your plants.

During Your grow space is a closed growing system, and the grow light is energy. Most of the light generated by grow lamps is converted to chemical energy and stored by plants, but the unused light is absorbed and turned into heat by the objects in the growing space. The biggest advantage of LED grow lights is that most of the wavelengths they generate are hemp plants that can be easily absorbed.

On the other hand, HID grow lights produce many more wavelengths than your plant really needs, and eventually only heat your grow. HID grow lamps also rely on heat to emit light first –   in fact, there is so much heat that it may cause a fire in a confined space. Combining this inefficiency with what LED produces more light per watt than HID lights, you can understand why LED grow lights generate less than 40% of the heat in growth space than HID. LEDs are generally more efficient than HID.

LEDs can provide more light per watt and project more light to where it is needed. The efficiency of hid, including HPS, is about 0.7 – 1.0 umol / J at lower wattage, but the efficiency increases with the increase of wattage. Very low end LED grow lamps, usually operating at 0.7 – 1.0 μ Mol / J, equivalent to low power HID. High quality LED grow lamps operate at about 1.5 umol / J, and high-end LED grow lamps (high-end cob and QB led grow light ) reach 2.0 – 2.5 umol / J.

HIDs and LEDs produce exactly the same amount of heat, but led grow lamps usually require less watts to emit the same amount of light useful to plants.

In short, yes, the LED grow lights does produce heat, but its heat is much lower than that of HID.
