How To Choose A Retrofit Dimmable Recessed Grow Light?

Indoor plant lights can glow where and when the sun isn't shining, and they allow you to extend your plant's growing season; provide a year-round supply of flowers, healthy vegetables, and herbs; and allow your seedlings to grow ahead of time before planting outside.Due to the different spectrums, there are several types of grow lights on the market, ranging from simple incandescent, fluorescent to HID to LED lights.

HID Grow Lights

HID lamps are the brightest and very efficient, but they are also expensive; a 1000w HID lamp can produce the same amount of light as 50 40w fluorescent lamps.Within the HID category, there are several types of bulbs: high pressure sodium, metal halide, low pressure sodium, and mercury vapor; the only ones indoor gardeners need to worry about are high pressure sodium or metal halide.The most common sizes are 400w and 1,000w, with 400w providing enough light for a garden of about 15 square feet (1.4 square meters); a 1,000w lamp can cover an area of about 4.5 square meters; for rapid growth, each 0.09 A square meter can use about 25 watts of HID lights.Metal halide lamps are blue-white, which is good for leafy growth and keeping plants compact; it is best used as the primary light source; a single bulb can last about 10,000 cumulative hours. (The bulb will last for over 10,000 hours, but the light will decrease, so it's best to replace it before it burns out) Metal halide lamps are also a lumen power source. They produce up to 125 lumens per watt, compared to 39 lumens per watt for standard fluorescent bulbs and 18 lumens per watt for standard incandescent bulbs. High pressure sodium lamps are reddish-orange and best for flowering plants. It is also economical because its average lifespan is twice that of metal halide lamps. High pressure sodium lamps produce up to 140 lumens per watt. Their main disadvantage is that they do not produce light in the blue spectrum. If HPS is the only source of plants, the plants will grow lanky, which is not the type of plant most gardeners want.How often grow lights are on should depend on the plant and its needs, most plants and vegetables need about 10 to 12 hours of light per day to grow; plants that produce fruit or flowers need more: up to 16 hours per day.

LED Grow Lights

LED plant growth lights use LEDs as luminous bodies, which can provide the required light conditions for plant photosynthesis in an environment lacking sunlight, so that plants can grow and develop normally or better; LED lights have strong roots, promote growth, and regulate Flowering period, flower color, promoting fruit ripening, coloring, improving taste and quality, etc.In recent years, new LED lighting technology has developed rapidly; as the fourth-generation new lighting source, LED has many characteristics different from other electric light sources, which makes it the first choice for energy-saving and environmentally friendly light sources.Compared with the previous three similar products, LED grow lights are more powerful and efficient, and they cost less, they save electricity and generate less heat; less heat allows the grow lights to be closer to the plants without worrying about Plants will be scorched.Because of this, LED lights can effectively promote better plant growth, so LED grow lights are widely adopted around the world.LED grow lights also have the following characteristics: rich in wavelength types, which are exactly in line with the spectral range of plant photosynthesis and photomorphology; the half-width of the spectral wave is narrow, which can be combined to obtain pure monochromatic light and composite spectrum as needed; it can concentrate light balance of specific wavelengths Irradiating crops on the ground can not only adjust the flowering and fruiting of crops, but also control the plant height and plant nutrients; the system generates less heat and occupies less space, and can be used in a multi-layer cultivation three dimensional combination system to achieve low heat load and miniaturization of production space.The advantages of LED light source are high luminous efficiency, long service life, safety and reliability, environmental protection and energy saving, so the prospect of LED in the lighting market will be more concerned.
