The Best 660 Watt LED Grow Lights for Indoor Plants

Cheap, energy-efficient, durable LED grow lights are becoming more and more popular as home grow lights for both professional growers and for plant enthusiasts. Although certain plants prefer distinctive wavelengths, it is often the best practice to have grow lights that cover the full spectrum of the sunlight — after all, plants are using that kind of light for rather a long time

What Are Full Spectrum LED Grow Lights?

First things first, if you’re new to indoor gardening, you’ll want to know exactly what you’re looking for. Full-spectrum LED (light-emitting diode) lighting aims to mimic natural sunlight, producing, as the name implies, the full spectrum of light plants require for optimal growth.

This full-spectrum is produced in two ways. One is by coating blue LEDs with a mixture of different colored phosphors. Phosphors convert the blue light’s wavelength into a wider range of wavelengths that ultimately look like white light (like sunlight does). The second is to combine red, green, and blue diodes in such a ratio and pattern that the light appears white to the human eye.

Full-spectrum LED lights are a relatively new technology. High-intensity discharge (HID) and compact fluorescent (CFL) lighting have been the standard for indoor growing but none of these lighting systems replicate daylight in the way LEDs can. As LED technology improves, they’re more and more becoming a viable option for growing and maintaining healthy plants.

Pros and Cons of Using Full Spectrum LED Grow Lights

Pros

Spectrum
Perhaps the biggest advantage to using full spectrum LED grow lights is right there in the name. Since they consistently put out the entire spectrum of light that plants need throughout their growing cycle, you won’t have to change the lights.

Return on Investment
While LED lights cost more than other lights, they last longer. The average lifespan for an LED light is about 50,000 hours, miles ahead of HID lights, which last an average of 24,000 hours, and CFL, which last about 8000 hours. You’ll pay more upfront but you’ll ultimately get more light and need to replace your bulbs less with an LED system.

Energy Efficiency
There’s no real comparison between LED lights and other types of grow lights. LEDs use about 75% less energy than other kinds of lights, according to the U.S. Department of Energy. If conserving energy or saving money on utilities is high up on your priority list, LED is really the way to go.

Heat
Heat is much easier to control in your growing space with full-spectrum LED lights. They generate much less heat than other kinds of bulbs, which can make them ideal if you’re growing in a small location or in a region with warmer outdoor temperatures.

Size
LED lighting systems are generally less bulky than other kinds of systems. HID lighting requires separate ballasts and reflectors, not to mention vents to manage excess heat. In smaller spaces, LEDs let growers maximize the room they have by allowing them to place plants closer to the lights themselves.

Cons

Cost
LED grow lights are more expensive than other kinds of lights like fluorescents or HID. The initial cost for setting up an LED system can be prohibitive.

Power
HID lights are much more powerful than LEDs. They’re able to generate a light intensity that encourages plant growth in a way LEDs can’t match. If you’re growing a high number of large plants, HIDs might still be the way to go because their light can penetrate foliage further than LEDs can.

Blue Light Exposure
Prolonged exposure to blue light, while necessary for plants to grow, is harmful to humans. It can damage your retinas, so working in your growing space will require you to be careful and to wear grow room glasses. You only have one set of eyes!

Full Spectrum Grow Lights Buyer’s Guide

Buying the right full spectrum grow light is crucial to the well-being of your indoor plants. And not all of them are built in the same way. So, you need to keep in mind a few important features before moving on to choose a suitable light.

Switches
Generally, a full spectrum grow light provides sufficient light for all stages of plant growth. However, some of you might prefer products that let you control the type of light that the plants would get. These products feature switches that help in adjusting the different light modes suitable for different growth stages.

Cooling System
This is an important criterion to consider when you’re looking for a grow light. You should ensure that the light has an efficient heat dissipation system. While some products consist of mute fans, others have an aluminum heat sink that absorbs the extra heat. Note that some grow lights with fans may produce an annoying noise sometimes.

High Wattage
For providing your plants with good coverage and the ideal light output, you should find a spectrum light that offers a minimum of 300W. Though, a single plant or small crop can thrive with a light having a lower wattage.

Many of the LED lighting systems available currently offer a wattage going up to 1000W. Note that a wattage higher than this will need a much bigger room or grow tent and an air conditioning system as well.

Conclusion

LED grow lights are becoming more and more popular with home gardeners and commercial cannabis growers. As technology and price points become more and more attractive every day, LED lights may be a great choice for your next growth. Since quality and overall value can vary greatly, be sure to do your homework before buying, double-check product specifications, read user reviews, and talk to other growers.
