Differences In Grow Lighting Types


LED grow lights can provide a wide variety of light to meet your specific needs. These lamps use less energy than other lamps, reducing your electricity bill and carbon footprint. They also generate very little waste heat. Not only does this help minimize their impact on your HVAC system, it also means you can safely install them closer to your warehouse. This helps reduce light loss and allows multi-stage cultivation.


  • LEDs are more energy efficient and environmentally friendly than other lighting options.

  • LEDs are available in a variety of colors.

  • LED lights give off heat. This means you can safely mount it just 12 inches above the canopy.

  • LEDs are more efficient and deliver an increase in micromoles per watt. Each watt of lighting, regardless of lighting type, generates 3.41 BTUs of heat. Using fewer watts reduces heat, reducing the overall tonnage required for cooling.

  • Depending on where you are located, manufacturer discounts may be available.

  • They last a long time and don't require the effort and expense of changing light bulbs regularly. A suitable LED lamp should carry a 5 year warranty and a life expectancy of 5-7 years depending on typical usage.

  • LED lights can be dimmed without changing the spectrum.


  • LED grow lights tend to be more expensive than other lights. While the initial investment may be higher, there is potential for price reductions and energy savings that can help offset the initial cost.


People have been using fluorescent lights to grow houseplants for years. These lamps are relatively inexpensive to purchase and operate. However, there are some disadvantages to using fluorescent lamps which is why more and more manufacturers are opting for LEDs.


  • Neon lights are easy to find and widely available.

  • Some fluorescent lamps are compact, meaning they fit easily in a standard light socket. CFLs are especially useful in small spaces because they don't require ballast or shop lights.

  • Cheap neon lights.


  • These lights give off heat that can damage plants if installed too closely.

  • Fluorescent grow lights generally have fewer micromoles per watt than other grow lights. This means that you need more fluorescent lamps and higher wattage to produce the same amount of light as other types of lamps.

  • Fluorescent, high intensity discharge (HID) and fluorescent lamps contain small amounts of mercury which is highly toxic and is considered hazardous to the environment.

  • They require frequent lamp replacement.


HID (High Intensity Discharge) lights produce a lot of light, although many of today's LED grow lights can match and exceed the intensity of HID lighting. HID lamps consist of a gas-filled tube and electrodes, and electricity reacts with the gas to produce a bright light.


  • Compared to LEDs, HID grow lights have a relatively low initial cost and produce a lot of light. This makes it ideal for growing cannabis or other plants that require a lot of light.


  • HID bulbs eventually wear out. To get the most out of these lights, it's important to replace the bulb frequently. You will usually replace these bulbs annually or suffer from loss of light and yield loss as a result.

  • HID lamps usually require a warm-up period after being turned on to reach full intensity.

  • HID grow lights require more power than LEDs. An increase in watts increases BTUs, and this requires an increase in cooling capacity.

  • HID lighting radiates heat, which requires the light to be further away from the plants.

  • HID lighting is not suitable for vertical grow racks because of the distance between the bulbs and the plant canopy.

  • Dimming HID lamps changes the output spectrum significantly and can be detrimental to your crops.
