Also, you can plug most LED grow lights directly into your regular electrical outlets.

Not needing these features saves space and also allows you to avoid the hassle of having to figure out how to assemble your lighting system. This is important for indoor growing because the farther away from a light source a plant is, the less energy is available to the plant for photosynthesis.Therefore, the closer the fixtures, the better the light efficiency.Īnother advantage of LED grow lights is that you don’t need a ballast to limit the current, or directional lenses, which send light exactly where it’s needed. The second reason is that a lower heat output makes it possible to place lights closer to the plants. The first is that lighting that gives off a lot of heat can easily create unacceptable temperatures in the confined space of a grow room, so you need a cooling system, which runs up your electricity bill. Lower running temperatures of LED grow lights are advantageous in hydroponics for a couple of reasons. Features such as the built-in heat sink, which pulls heat away from the lamp and dissipates it into the air, also help improve brightness and longevity. The impressively long lifespan that LED grow lights offer is also due to the fact that they are solid state, rather than having vacuum or gas components that deteriorate over time.
Their solid state technology has been a real revolution in lighting efficiency. Benefits Of LED Grow LightsĪmong the many benefits of LED grow lights, the biggest ones are that they are energy efficient and very long lasting.Įnergy-efficient lighting is an obvious advantage for hydroponic gardening, and LED grow lights are famous for this. CFL grow lights differ from regular CFLs in that they come in larger sizes, provide higher wattages, and put out a broad spectrum of light.Fluorescent tube grow lights come in different sizes and varieties, although the T5 diameter high-output (HO) grow lights, which emit about twice as much light as regular fluorescent tubes, are widely considered the best ones to use.Fluorescent grow light fixtures typically have built-in reflectors and ballast, which give them a thin profile.
The color of the light is determined by the chemical composition of the phosphor.įluorescent grow lights come in two forms: compact fluorescent lights (CFL) and fluorescent tubes. What Are Fluorescent Grow Lights?įluorescent lamps convert electrical energy into light by running a current through mercury vapor to produce ultraviolet radiation, which stimulates the coating of phosphor powder on the inside of the lamp to fluoresce, thus producing visible light. They feature additional cooling systems to increase their efficiency. Today’s LED grow lights are designed to emit wavelengths of light that produce the natural daylight spectrum, or they can be precisely adjusted to put out ideal wavelengths for the varying needs of growing plants. An LED lamp is made up of an LED mounted to a heat sink, along with directional lenses and a power supply.
An LED may be configured either as a single-die emitter that’s mounted on a circuit board, or an array of dies mounted directly on a circuit board, which is known as a chip-on-board (COB) module. A form of solid-state lighting, an LED uses a semiconductor chip, known as an LED die, that turns an electrical current into photons through a process called electroluminescence. We’ll begin with a short introduction to each type of grow lighting, then run through the pros and cons of each type, followed by a head-to-head comparison of LED vs fluorescent grow lights. So this article will consider two of the most popular systems available today: LED vs fluorescent grow lights. But sorting out the dizzying array of grow lighting that’s available is a daunting task, especially if you’re new to hydroponics. And it is often the biggest expense, considering the cost of investing in a grow light system and the heavy use of lighting, at 12 or more hours a day, every day. Lighting is one of the most important aspects of any hydroponics grow room.
