Plants don’t use a lot of energy producing light at ranges that are not efficient. CMH are a better single light solution because of their PAR efficiency. There is a more natural color rendering index.

What’s better CMH or HPS?
HPS bulbs have around 3% blue in the spectrum, which is less than the other bulbs. Ceramic Metal Halide bulbs have recently been added to the market. They are more expensive per watt, but they have a better spectrum and are more efficient.
Are CMH lights bad for your eyes?
This type of lighting isn’t any better for your eyes. A large amount of UV light is emitted by CMH. There are a number of effects of UV exposure on humans.
Is CMH full spectrum?
High quality light is produced by Ceramic Metal Halide grow lights. The quality of sunlight is mimicked by the light they produce. Some UltraViolet and InfraRed light will be produced by the grow lights.
What lights do professional growers use?
The majority of growers use HPS lights and T5 lights during at least one growth stage, while more than a quarter use LEDs.
Is CMH better for veg or flower?
Ceramic Metal Halide bulbs have recently been added to the market. They can be grown from seed to flower with one bulb. The high percentage of blue in the spectrum will result in less stretching in the flower stage and more growth in the veg stage.
Is CMH good for flowering?
HPS bulbs are better for flowering than the CMH bulbs. They are the perfect full cycle bulbs because of their improved vegging. CMH lamps make up for their higher cost with double the usable lifespan.
Is CMH or LED better?
HPS’s put off more heat than CMH’s, but they don’t have as much heat. The savings depends on other factors such as the grow space and the amount of power used for cooling. Replacing bulbs is an additional cost that a CMH grower will be aware of.
How long do 315W CMH bulbs last?
They give you a huge output, even though they only consume 315 watt. They have an open rated construction that reduces the heat from the tube. The kit runs cooler than a similar light. The lamps are expected to last 20,000 hours.
Why is HPS better than LED?
The heat per watt is more with an HPS fixture than it is with a LEDs. This technology produces less heat and has a higher wattage equivalency than HPS, which is why it is more efficient in transferring energy to light.
What’s better LED or HPS?
In comparison to HPS lights,LED grow lights are very energy efficient. HPS grow lights use a lot of energy while high qualityLED grow lights use a lot of energy. Long term savings can be found in the fact that LEDs have higher upfront costs than HPS lights.
What’s the difference between HPS and CMH?
You can get 130,000 lm in a single light with a 1000 watt HPS bulb. The highest amount of lm CMH lights can be found at 72,000 to 75,000. The HPS bulb is three times more powerful than the CMH bulb.
What is a CMH light?
The ceramic discharge metal-halide (CDM) lamp is a source of light that is a type of metal-halide lamp which is 10 to 20% more efficient than the traditional metal-halide lamp.
Can HPS lights damage your eyes?
Without proper safety precautions, high pressure sodium lights can cause serious damage to the eye. People working in grow rooms need to take proper precautions to protect their eyes because of the damage done.
Can you veg under HPS?
The answer is yes, if you want to use an HPS bulb for veg. You can use any light you want for any stage of growth, but the real question is how well each bulb works for veg.
What color light is best for your eyes at night?
Green lights can help regulate the body clock. The clock can be thrown off because of exposure to green light at night. It has been proven that yellow light protects the eyes from excessive blue light.
Are CMH hotter than HPS?
The grow room may need to be heated up in the winter due to the lower heat output of the LEDs. The HPS’s put off more heat than the CMH’s do.
Do CMH lights run hot?
The CMH systems use ceramic, which gives you a perfect spectrum of light, while the standard metal halide bulbs use a tube. That’s why it works at higher pressure.
Are CMH lights dimmable?
The Digital Greenhouse CMH 315 watt ballast has exclusive dimmable technology that allows growers to operate the system with different lamp outputs. The system has a professional grade reflective system.
Are LED lights safe for human eyes?
The lights are very bright and can cause harm to your eyes. With today’s high power LEDs, this is truer than it has ever been. Don’t wear sunglasses if you look directly into the lights. The bottom line is that LED grow lights are not as dangerous as other types of grow lights.
