Are MH and HPS bulbs interchangeable

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. … These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs. Their operation is a bit different and they therefore require different ballasts.

Can you use a HPS bulb in a MH fixture?

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. … These bulbs cannot be interchanged without changing their ballast, the regulating element in all light bulbs. Their operation is a bit different and they therefore require different ballasts.

Can you use a HPS bulb without a ballast?

You can’t run an HPS bulb without a fitting ballast. At best you’re going to break the bulb, and in the worst case scenario you’re setting an explosion up. A ballast is what powers your HPS bulbs.

What is the difference between MH and HPS bulbs?

Metal Halide (MH) lamps provide more of the blue spectrum, which is ideal for leafy crops, and/or plants that are in a vegetative stage. … High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.

Can I use a higher wattage metal halide bulb?

However, newer ceramic arc tubes do allow higher wattage MH bulbs and arc tube temperatures, which manufacturers claim also results in better efficacy, color rendering, and color stability.

What is better for flowering HPS or MH?

Ironically, most HID grow light enthusiasts recommend using both MH and HPS grow lights. MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.

Which is better metal halide or high pressure sodium?

Metal halide is much less efficient than high pressure sodium–MH produces much less light per watt; MH produces more glare due to the blue light component and increases adaptation time; MH more effectively shuts off melatonin production which can trigger tumor growth; MH contains more mercury within the bulbs; MH …

Do metal halide bulbs require ballast?

Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. … Regulating lamp current and power: The ballast regulates the lamp operating current flowing through the lamp after the lamp has been started.

Can I replace metal halide with LED?

LED Offers Long Life, Lower Energy Costs, Instant On and Control Options. … A 400 watt metal halide bulb can be replaced with a 200 watt LED. A 100 watt metal halide can be replaced with a 50 watt LED. Implementing an LED replacement program should result in a 50% reduction in annual energy use (kWh) costs.

Can HPS lights be used for veg?

In response to the general question, can you use an HPS bulb for veg, the answer is yes. … Basically you can use just about any light out there for any stage of growth, the real question is how well do each bulb work for veg.

How hot is a 600W HPS?

When factoring in the heat given off by a luminaire, the BTUs are calculated off of the total wattage of the luminaire. If you have a 600 Watt HPS lamp, the BTUs for that luminaire are the same as a 600 Watt LED. A single watt of power is equal to 3.41 BTUs so a 600W luminaire will produce 2,046 BTUs.

Why do HPS lights need a ballast?

HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.

Can you put a metal halide bulb in a regular light fixture?

Like fluorescent lights, metal halides require a ballast to provide high starting voltages and to regulate current inside the bulb during operation. … This is why a metal halide bulb will not work in a standard household lighting fixture — aside from the fact that the larger E39 base will not fit.

Is metal arc the same as metal halide?

Compared to standard metal halide lamps, METALARC PULSE START lamps reach 90 percent of full light output 30 percent faster and have a 60 percent shorter hot restrike time. METALARC PULSE START lamps may be combined with SYLVANIA HID ballasts to form a complete system.

Can you use a 250w bulb in a 400w ballast?

Sure, you can do it… it might explode, but you can do it.

Can you use metal halide for flowering?

Supposedly, the blue-light-intensive spectrum of MH lamps fairs best for vegetative growth, while the red-light-intensive spectrum of HPS lamps grow the best buds when it comes time to flower. … A long-day plant (LDP) flowers when it experiences the increasingly longer days of Spring and Summer.

Why do metal halide bulbs explode?

Metal halide (MH) lamps can explode (typically referred to as sudden nonpassive failure) because they operate at high pressures, but some products are manufactured with safety features to prevent injury. … Some MH lamps are self-extinguishing-they will automatically extinguish if the outer envelope is broken.

Is metal halide better than LED?

LEDs tend to last much longer and are a more energy efficient and less maintenance intensive technology. Metal halides have long warm-up periods and a shorter lifespan but produce a very high quality light and are one of the most efficient lights when it comes to very cool color temperature outputs.

How much area does 600W HPS cover?

600-Watt HPS grow lights are the most efficient HPS grow lamp. 600W HPS grow lights produce more light output per Watt used than other wattages and cover around 36 square feet. 1000-Watt HPS grow lights are the most powerful and cover a wider area of around 49 square feet.

How far should a 600W HPS be from seedlings?

Unlike LED grow lights, HPS lights produce more heat, so growers need to know how far to put HPS lights from plants. The HPS distance from seedlings should generally be between 10 and 14 inches from plants.

What is the best 600W HPS bulb for flowering?

Are metal halide bulbs being phased out?

Phasing out A number of popular lighting types will have to be phased out by 2017 including selected ‘standard’ high-pressure sodium (including retrofit), high-pressure mercury, and standard performance metal halide.

How do you convert HPS to LED?

1. 70 watt HPS = 40 watt LED.
2. 100 watt HPS = 50-60 watt LED.
3. 150 watt HPS = 80-90 watt LED.
4. 250 watt HPS = 90-125 watt LED.

Can you touch metal halide bulbs?

You should be extremely careful never to get skin oils or anything else on a small MH lamp (the small ones are around the size of a fingertip or so). This will definitely harm the lamp and can cause premature failure.

When should a metal halide bulb be replaced?

In the case of Metal Halide, most manufacturers rate these HID light bulbs with a life of approximately 20,000 hours. This rating traditionally means the point in which 50% of the lamps will fail, but in the case of maintenance, this is the DO NOT EXCEED time of all lamps. At this point, all lamps should be replaced.

What voltage are metal halide bulbs?

Most metal halide ballasts operate on 120-277V. These are called 4-tap ballasts and they operate 120/208/240/277V.

How long do metal halide ballasts last?

Most high quality ballasts have a life expectancy anywhere from 20,000 to 60,000 hours. The life is greatly dependent on operating temperature and the quality of components used.

Is HPS better than LED?

LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light. … All too often, the µmol/joule rating on HPS products states the lamp efficiency, not the actual product efficiency.

What is MH HPS?

MH, or Metal Halide, and HPS, or High Pressure Sodium, are two types of High Intensity Discharge lights that give a brighter effect, and also help to save energy. Both the MH and the HPS are widely used for outdoor lighting. Well, both these lights have specific characteristics that differentiate one from the other.

What is MH Growlight?

Metal Halide (MH) lamps typically emit a white colored light. Traditionally Metal Halide lamps have been used by indoor growers during the vegetative stage of plant growth. They are ideal for growing plants up to the flowering and fruit production stages because they mimic the spring/early summer seasonal sun.

WHAT LED is equivalent to 600W HPS?

Some LED systems outperform an optimised HPS system and achieve much better efficiency. This means you can grow more with the same or smaller footprint. The MIGRO 400 is highly efficient at 2.0 µmols/watt PPFD. Replace a 600W HPS system with a MIGRO 400 LED and the power consumption reduces from 640 watts to 370 watts.
