What Are HID Grow Lights?
High Intensity Dischargesamsung 301h led grow light , as the name suggests, are prized for the brightness and intensity of the light they emit. Light that’s intense enough to easily penetrate the canopy and nourish your whole plant.
How Do HID Grow Lights Work?
The technology behind HID Grow Light has actually been around for centuries. Gas is enclosed within a glass bulb, along with electrodes. When electricity is passed through the bulb it forms an arc between the electrodes which heats the gas molecules. This causes the gas to give off light. Brightness and color of light depends on which gas the bulb contains.
The two main kinhttps://www.growpackage.com/collections/eco-farm-led-grow-lightsds of HID bulb you’ll find within grow lights are MH Grow Lights(Metal Halide) and HPS Grow Lights (High Pressure Sodium).
MH bulbs emit a cooler, bluish spectrum that’s ideal for the vegetation stage of growing.
HPS bulbs, on the other hand, create a predominantly orange to red spectrum, that will look yellow or gold to the human eye. HPS bulbs are ideal for flowering, but can also be used for the whole grow cycle if needs be.
However, there’s more to an HID light than just the bulbs.
Advantages of HPS Grow Lights
HPS grow lights are capable of producing an intense amount of light, which can increase cannabis flowering.
There are a wide variety of HPS grow lights available, so options have become more standardized.
The initial start-up costs are lower with HPS grow lights than LED lights .
Drawbacks of HPS Grow Lights
HPS grow lights require more power and are less energy efficient than LED lights150w cmh grow light.
HPS grow lights have a shorter shelf life in comparison to LED lights.
The intense lighting of HPS makes adequate airflow and ventilation essential. 
Setting the optimal temperature can be challenging, particularly in confined spaces.
HPS grow lights increase costs substantially in the long-term
How Do LED Grow Lights Differ From HID?
LED grow lights use LED chips rather than any sort of bulbs. The chips or diodes turn electricity directly and efficiently into light. Like HID lights, certain colors of LED chips are more energy efficient than others. However, even so, an LED grow light will use far less energy or wattage than an equivalent HID. 50-70% energy savings are quite normal to see.
You won’t have any hoods or ballasts to worry about either. Because LED grow lights are basically plug and play. Hang up your unit, plug it in at the wall, turn it on.
Raising and lowering the height for different grow stages is really about as inconvenient as it’ll get. And if you want to change spectrum for different grow stages, simply flick a switch. In fact, some can even be controlled and fine-tuned by touchscreens, WiFi, smartphone apps or remote control, or set to an automatic program. All of which save you trying to reach the light above a full, flowering canopy.
The other major difference is how cool LED grow lights run compared to HIDs. Not only is less energy wasted creating heat, less electricity is wasted cooling them (40-50% less). Moreover, the design of most full specturm led grow light units makes sure that whatever heat is produced is mostly directed up and away from the plants.
Advantages of LED Grow Lights
LED grow lights are more energy efficient. They produce the same amount of light as HPS lights but consume substantially less energy.
LED grow lights do not produce as much heat as HPS lights, avoiding the need for additional ventilation or airflow systems.
LED grow lights are smaller than HPS lights, maximizing grow space.
LED grow lights feature an impressive shelf life.
Drawbacks of LED Grow Lights
LED grow lights require a higher upfront investment. However, they can reduce costs in the long run due to their extensive shelf life.
LED grow lights may not produce enough heat as HPS lights for colder climates
LED lights lack standardization, which makes comparing options more challenging. However, we’ve compiled a list of the top quality and best priced LED grow lights for you!
Advantages of LEDs over HPS 
Efficiency – LED diodes are very electrically efficient, which could save you money over time (though the jury is still out when it comes to whether LEDs get better yields than HPS watt-for-watt). Additionally, where an HPS bulb needs to be replaced every few grows to maintain its brightness, individual LED diodes keep their brightness practically forever. With an LED grow light, it’s almost certain something else will break on the lamp before any diodes start losing their brightness.
Plug-And-Play – LED grow lights are plug-and-play which means you can simply hang up the lamp over your plants and plug it directly into any standard electrical socket. HPS lighting requires the use of a ballast; for smaller models it can be built-in, but larger HPS lights generally need a brick-sized external ballast.
LED Grow Lights Come With Built-In Cooling – Along the lines of being totally plug-and-play, most LED lamps have heatsinks and small built-in fans to help disperse heat up and away from the lamp, which lets them run cooler. On the flip side, even a small HPS bulb needs extra help for cooling, usually by venting out hot air using a fan and ducting.
Customized Color Spectrum – It is known that the color spectrum of light affects how plants grow. Unlike other grow lights which are pretty set in their color spectrum, each LED diode can be configured to emit light of a very specific color spectrum chosen by the user. This means that LED grow light color spectrums can be adjusted and customized in a modular way that’s impossible to achieve with any other grow light.
Conclusion—HPS is Good, LED is Better
Virtually any type of artificial light has, at some point, been used for horticultural purposes. Since greenhouse operators and the space agencies both share an interest in determining which light sources produce the best results while consuming the fewest resources in terms of energy (to run the light and to cool the grow area) and grow space and cooling, a large number of studies have been, and will be, conducted to determine which artificial light sources are the most effective and efficient.
Since high-pressure sodium lights produce an intense light at a relatively low cost, they are widely used in horticulture. However, they do not emit the ideal combination of colors and they also produce a large amount of heat. As a result, more energy is needed to run the lights and even more to cool the growing area. Furthermore, the lights must be kept far from the canopy to prevent leaf-burn.
LED grow lights for indoor plants, on the other hand, require less electricity to run and, due to their lower production of excess heat, less electricity to keep down the temperature of the grow space. They lower heat also means no burn damage to plants—in many cases, even when there is extended leaf-on-bulb contact. Finally, LED fixtures can be customized with the optimal ratio of colors for plant growth. All of this means you get better growth and higher yields at a much lower cost.
