HPS is two times more efficient than metal halide. The delivery of usablePAR is better with HPS than it is with metal halide. An average of 80,000 to 110,000 lm per standard 1,000 watt bulb is delivered by metal halides.

What’s better MH or HPS?
Higher light intensity (lm) is provided by the HPS lights. The more light you use, the better the results.
What’s the difference between HPS and MH lights?
The blue spectrum provided by metal Halide lamps is ideal for leafy crops and plants that are in a vegetative stage. Most plants that are active in fruiting and flowering will benefit from the yellow/red spectrum provided by HPS lamps.
Is HPS still the best?
HPS lights are the most popular type of grow light used today. HPS grow lights are used by a lot of commercial growers. It’s no wonder that HPS lights have a good reputation. It’s easy to use.
Can I use a MH bulb for flowering?
The lack of red wavelength in the lights’ spectrum makes them not good at flowering plants alone. Growers use vegging and HPS bulbs for flowering because of this. They use both bulbs at the same time.
Is 400 watt HPS good enough?
The most common sizes for bulbs are 400W, 600W and 1000W. 600w HPS bulbs are the most efficient, while 1000w HPS bulbs are the most powerful.
Why is HPS better for flowering?
During the later stages of plant growth, HPS bulbs are the preferred type. Plants will begin to produce flowers and fruit in those stages. HPS bulbs are great, but not ideal because they want a lot of red spectrum light.
Is LED or HPS better for flowering?
The same things happen with LEDs. Even though they’re more efficient than HPS, some LEDs are less efficient than high quality HPS fixture and give you less light. The lamp efficiency is not always stated in the mol/joule rating of HPS products.
Why is HPS better than LED?
The heat per watt is more with an HPS fixture than it is with a LED one. 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.
Why do commercial growers use HPS?
HPS bulbs give an incredible amount of light which can be used to produce great results. It’s easier for growers to compare bulbs and set ups when they know the HPS lights are standardized.
Can you switch from HPS to LED?
If you switch to LEDs, you can save 50% on lighting energy costs. But it goes on and on. The LEDs emit less heat than the HPS lamps. When you switch from HPS to LEDs, you have to cut down on supplemental cooling.
What is better metal halide or high pressure sodium?
Metal halide is less efficient than high pressure sodium, it produces less light per watt, it produces more glare due to the blue light component, it has more mercury in it’s bulbs, it has more melatonin in it’s bulbs, it has more mercury in it’s bulbs,
Is metal halide the same as high pressure sodium?
There is a difference between metal Halide and high pressure sodium. The Metal Halide and High PressureSodium bulbs are part of the HID family. The light emitted from a High Pressure Sodium bulb is amber orange while the metal halide light is white.
Is MH better than HPS?
Higher light intensity (lm) is provided by the HPS lights. HPS grow light bulbs are more efficient and last longer, but they are less efficient towards the end of their lives and should be replaced before they burn out completely.
What are high pressure sodium bulbs used for?
In large manufacturing facilities and as plant grow lights, high pressure sodium lamps are often used. There is mercury in them. They are widely used for outdoor area lighting.
What color light is high pressure sodium?
High pressure sodium lamps are part of a family of high intensity light bulbs that put out a lot of light. An orange white light is produced by a combination of metals and gasses inside a glass tube.
Can you replace a high pressure sodium bulb with a metal halide?
The Metal Halide and High PressureSodium bulbs are part of the family of bulbs. The regulating element in all light bulbs needs to be changed. They need different ballasts because of their operation.
Do high pressure sodium bulbs use a ballast?
HPS lamps need to regulate the current flow and deliver the correct amount of power to the arcs. HPS lamps don’t have starting batteries. A high voltage pulse is generated by the electronic starting circuit in the ballast.
Can you put a metal halide bulb in a regular light fixture?
Like fluorescent lights, metal halides need a ballast to regulate the current inside the bulb. The larger E39 base won’t fit in a standard household lighting fixture and a metal halide bulb won’t work in it.
Can I replace a high pressure sodium bulb with LED?
Even though there is a lot of talk of LED lights, high pressure sodium bulbs are still used for lighting. A higher watt high pressure sodium bulb can be replaced with a lower watt LEDs because they are better at controlling the light.
Can I use a high pressure sodium bulb in a mercury vapor fixture?
In exterior locations, Incandescent and mercury vapor lamps should be replaced with metal halide, high pressure sodium and/ or low pressure sodium lamps.
