The type of gas and chemicals used in hid grow bulbs like mercury and metal halides react with each other to give you light.
Metal halide vs led for growing.
Although these two examples are polar opposites they still ask the same question.
That heat is pretty intense and will radiate from the bulb.
Mh lights are more efficient at creating light than fluorescent and induction lights but are less efficient than hps and much less efficient than leds.
But keep in mind that much of the light that the light meter is reading from a metal halide isn t even visible.
As the bulb gets brighter and brighter it gives off heat.
One of the biggest advantages to growing with leds as compared to growing with high intensity discharge hid bulbs like high pressure sodium hps and metal halide mh bulbs is that leds consume a fraction of the electricity as much as 60 less.
The modern hobby and commercial cultivator now have the power to dial in spectrums specific to the plant strain they are growing.
Unlike led s hid grow lights work because of gasses not wires or chips.
It s your job to adequately determine a few factors before you begin searching for the best grow light whether it be metal halide hps led or cfl bulbs.
When factoring in the spectral efficiency led grow lights can offer metal halides are significantly less efficient.
Efficiency of metal halide vs.
We have an array of modern light systems that can grow plants like ceramic metal halides cmh and light emitting diode led systems.
Over the past twenty years grow lights have evolved.
Another advantage of leds is their low heat signature.
Are you growing in a grow tent or in a warehouse.
Let s take cmh vs led grow lights head on.
A big advantage of leds over metal halide grow lights is their significantly lower heat output.
