In this LED vs. HID part, we will describe how the advent of LED has superseded the traditional HID(High-Intensity Discharge) bulbs.

HID bulbs take the shape of the tube.

The HID bulbs are classified as HPS and MH because of the gas-filled inside it. HPS stands for High-Pressure Sodium, whereas MH stands for Metal Halide.

Now, the main problem comes while you have to change the color or spectrum of the LED. In case of HID bulbs, you have to change the bulbs itself. This leads to much inconvenience.

Here comes the main advantage of LED bulbs, ‘Adjustable Spectrum.’ This adjustable spectrum supports each phase of plant growth. You may change the color as well as the intensity of light as and when needed.

There is no need to change the bulbs every now and then, suiting the needs of plants.

Also, LED come in different variants like panels, emitters, saucers, and bars. Thus, LEDs are more versatile than traditional HIDs, and they have replaced the HIDs gradually.

Benefits of using LED

  • LEDs have a longer lifespan
  • LED lights are eco-friendly
  • The LEDs save 50-70% more energy than HID
  • LEDs come with effective heat management
  • It contributes to photosynthesis and flower production
  • LEDs leave no Thermal footprint

Photosynthesis Active Radiation, known as PAR, is a type of spectrum that is helpful in the process of photosynthesis. The band of spectrum, that is useful for the same is Visible light band. It has a wavelength from 380 to 720 nm.

Photosynthetic Photon Flux Density is the PAR that actually reaches the leaves of the plants. It is also referred to as ‘exact spots.’ The unit for PPFD is umol/m^2/s.

Actual Power Drawn
Higher the actual power drawn, the higher the PAR.
