Different types of grow light for indoor plants mainly used by growers today are flourescent lights, HID grow light (High intensity discharge) and LED grow light. It is only in recent years LED grow lights has gotten more traction in the marketplace, while older equipment HPS and MH grow light bulbs are becomming less popular among the consumers because of high electricity bills, too hot temperature in grow room, the constant change of bulbs and high risk of fire to name a few.

When it comes to growing cannabis, HPS grow light has been the stable workhorse for cultivators across the globe. However, there is an increasing trend of LED lights emerging, and the LED grow light industry is developing rapidly in both size and quality. So, we thought we would take a look at the two, and assess the pros and cons of each.
FORGETTING PREJUDICE

Log onto any cannabis growing forum, and you will easily find a heated debate about which is better: HPS or LED grow lights. Look back at posts from a couple of years ago, and HPS was the clear winner. Sure LEDs could get results, but for the higher initial cost, they were just not good enough to unseat the HPS light from its throne. However, as the years have gone by, LED grow lights 150w cmh grow light have come on in leaps and bounds in terms of technology and quality, and have substantially dropped in price. This has led to the arguments against them growing weaker and weaker. However, the debate still rages on, as those who have HPS in their blood are happy sticking with a tried and tested method, and more experimental growers sing the praises of their new fancy LED setups.

HPS Grow Lights
 have often been seen as the best grow light available. HPS grow lights produce a massive amount of light, which is especially good for flowering. However, they also produce a great deal of heat.

are relatively new to the cannabis growing scene, and had a pretty shaky start. They appeared with promises of increased yields, better growth, and higher potency, but for many, failed to deliver — especially where cheaper LED lights were concerned. This is why so many HPS growers remain sceptical of LED grow lights, because if something sounds too good to be true, it often is.

The Benefits Of LED Grow Lights

Here are some of the main benefits of using LED lights samsung 301h led grow light for your garden.

Operational costs

The primary advantage of LED grow lights are the lower operating expenses. Good LEDs cost up to 80% less to operate than equivalent HID bulbs.
Whether you use them as your main light source or just as supplemental lighting, they can begin to pay for themselves within 6 months of frequent usage, although most cost so much more initially, that is takes 2–3 years to break even.
And remember, the lifespan of an LED grow light generally ranges from 50,000 to 100,000 hours, which is 10–20 times longer than common HPS/MH grow light bulbs.

Increased Lifespan

LED grow lights have a lifespan of over 50,000 hours, which is much longer than traditional lighting systems. A large reason for this is the low operating temperature of the lights.

Conventional lighting systems produce a lot of heat, which reduces their lifespans significantly. The longer lifespan of LEDs means you can grow crops for many years without needing to replace the lighting systems, which reduces costs.

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.
Programming Options

One benefit of LED lighting is the ability for the grower to adjust the lighting to match the specific needs of the plant. For instance, the lights may be programmed to mimic a natural circadian rhythm — an advantage that is lost with archaic lighting techniques, such as HPS lights.

Cool Operating Temperature

LED grow lights do not give off a lot of heat. This is unlike HID lighting systems that produce temperatures approaching 400 or more degrees.
LED light does not much affect the operating temperature in a greenhouse or grow room. LED plant lights eliminate the need to install cooling systems in your grow area.
The Benefits Of HID Grow Lights
are one of the most common and turned to grow lights on the market. Key to the popularity of HPS grow lights, is their raw light output. Because of the unique light demands of the cannabis plant, the ability of these lights to produce a large amount of light is incredibly desirable. However, HPS grow lights also produce a significant amount of heat and the light they produce often requires enhancement by Metal Halide lighting for vegetative growth. This also means that many growers opting for HID lighting require separate veg and flowering lights or at least multiple bulbs, adding to the overall expenses of maintaining an HID setup.

HPS bulbs provide an incredible amount of intense, raw light which lends itself to producing great yields.
Because they’re older, HPS lights are more standardized among different manufacturers, making it a bit easier for growers to compare bulbs and set-ups.
HPS lights have a lower start-up cost than LEDs. It is worth noting, however, that the price gap between comparable HPS and LED grow has become exponentially smaller each year.
Conclusion
Both LED grow lights and HPS grow lights are best cannabis grow light and equally capable of producing great yields, and both have advantages over the other. If initial cost is not an issue, the answer to which one is better really comes down to other main factors contributing to your grow such as the growing method you plan to practice as well as the ambient conditions and size of the grow area.
