LED grow lights have been around for a few years now. While perhaps a decade ago they didn’t quite live up to their full potential, now they are by far the best way to grow plants indoors.
Types Of Grow Lights
Grow lights come in three different forms of lighting; Fluorescent, HID, and LED. Fluorescent lights are ideal for plants with low to medium light requirements. A downside is that they can be costly and take time to reach desired temperatures. This could reduce the growth of your plants. High-Intensity Discharge (HID) grow lights can provide a cost-efficient light source. HID grow lights are cheaper than LED grow lights. Whilst less effective they are still a tried and tested option for many growers. Research now shows that Mercury levels in HID can have an effect on health and the environment. LED grow lights are great because they are energy-efficient. As well as being durable they can have an optimized spectrum for all phases of plant growth. LEDs are safe for the environment, don’t overheat, are cheap, and use low power.
Why Do You Need LED Grow Lights?
LED stands for “light-emitting diode” — LED lights aren’t light bulbs in the traditional sense but are rather semiconductors that convert electricity into light.
LED grow lights are specially designed LED lights that emit the right colors of light at a powerful enough intensity to help plants grow indoors. If you don’t have a grow light, most plants won’t get sufficient light to grow indoors, unless placed on a windowsill.
Some LED grow lights produce full-spectrum light, which is best at replicating real sunlight, whereas others produce a more limited spectrum.
HI-PAR LED Grow Light is built differently; with interchangeable LED bars for custom spectra, a wide-angle 120° output, pure performance diodes (Osram & Lumileds), and a unique high-performance driver for maximum efficiency! SPECTRO 240w is suited for rugged horticultural conditions -IP54 rated with novel passive cooling capability on each LED bar. More Light, Less, Power-SPECTRO 240w is perfect for vegetative and floral growth and will ensure heavy flowers and high-quality produce. All SPECTRO fixtures are compatible with HI-PAR Control Station V2. Dimmable 25%, 50%, 75% and 100%, with passive cooling function (no fan and no noise)

The AGLEX LED grow light is equipped with an upgraded SMD 3030 chip and 4 high-efficiency aluminum rods to ensure high-efficiency PPE 2.8umol/J, better heat dissipation, and longer service life. Compared with old plant lights, the output per watt can reach up to 2.8 grams, the average PPFD is increased by 30%, and the yield and quality are increased by 50%. Consuming only 240 watts, 448 LED lights, 4 x 4 feet (approximately 1.2 x 1.4 meters), 240 watts LED grow light M240 will help you achieve maximum quality and quantity. This plant growth light uses a special dimmer, which can precisely adjust the brightness. 0–10 levels are optional. This grow light can be folded, can be folded 180 °, the light design, easy to move and install, can be operated by one person. It is composed of full-spectrum white 3000K 5000K, red 660 nanometers, and infrared 740 nanometers, which are close to natural sunlight. The spectrum applies to the entire stage of indoor planting.

Considerations For Selecting LED Grow Lights
Ease of use
Indoor gardening can be challenging enough, without having to contend with complicated equipment. For your own sake, choose an LED grow light that’s easy to position and use. It should be very straightforward to switch between different wavelengths and levels of light intensity.
Wattage is one of the primary concerns when selecting an LED grow light. Plants need plenty of light to grow, but too much light can cause issues with nutrient deficiency, and result in browning or yellowing leaves. The amount of watts you need from a grow light depends on the type of plant you’re growing, and the area you need the light to cover. High-light flowering plants (like tomatoes) may need up to 32 watts of light per square foot of growing area, whereas low-light plants (like salad leaves or herbs) need more like 10 to 20 watts per square foot of growing area.
Type of plant
Think about the types of plants you’ll grow, and their light requirements. Some require full sun, whereas others may need lower light conditions. If you’re likely to raise a range of plants at different times, with different light requirements, dimmable LED grow lights are a good option, so you can turn down the juice when you’re growing plants that need less light. Blue spectrum light is important for strong plant growth, especially in non-flowering plants (or plants that aren’t yet in their flowering phase). Red spectrum light can help to encourage flowering.
Until relatively recently, LED grow lights had limited spectrums, usually offering red, blue, and white light. Nowadays, you can find full-spectrum LED lights, which provide all the colors in the light spectrum. Since full spectrum lights are the most similar to natural sunlight, they can support plants throughout the full growth cycle, from seed right through to fruiting, flowering, or producing vegetables.
The semiconductor chip is the core of your LED grow light and is what converts electricity into light. Lights with a good quality semiconductor chip are likely to be long-lasting. The chip itself has a wattage — we recommend purchasing LED grow lights with a semiconductor chip of at least three watts in order to provide an adequate amount of light.
Indoor gardening gets a lot easier with grow lights, and they enable you to cultivate plants at any time of year, in any climate.
