A high pressure sodium (HPS) ballast is used in conjunction with an HPS grow light. The ballast is responsible for igniting the gas in the tube, which creates the light. … Without a ballast, the light will burn to hot and pop.

Why do I need a ballast for a HPS light?

The ballast ensures that the lamp only receives the current it needs and nothing more. Without the ballast to regulate the amount of electricity going into the bulb, the light would continue to increase in intensity until the bulb blows. … The ballast automatically increases the amount of power to the bulb as it ages.

What is ballast and why is it used?

In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.

Can I use HPS without 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 does a ballast do for a grow light?

Grow light ballasts power high intensity grow bulbs and lamps by regulating the voltage to a high intensity discharge (HID) light or compact fluorescent light. Some ballasts power specific bulb types while others are “switchable,” capable of powering both HPS and MH bulbs.

Can you use regular fluorescent lights to grow plants?

The short answer is: any type of fluorescent light will help any type of plant grow, whether it is cannabis or lettuce or orchids. … While you can use any type of tube or bulb and see results, you want to provide the kind of light your plants want most.

Do LED grow lights need a ballast?

All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast.

Can I veg with 600W HPS?

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.

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's better HPS or metal halide?

HPS is about twice as electrically efficient as metal halide. Photosynthetically Active Radiation (PAR) is what really matters to plant growth, and delivery of usable PAR is better with HPS than metal halide. … Metal halides deliver, on average, about 80,000-110,000 lumens per standard 1,000-watt bulb.

What do modern ships use for ballast?

From the 1880s onward, ships increasingly used water for ballast, thereby avoiding time-consuming loading of solid materials and dangerous vessel instabilities resulting from the shifting of solid ballast during a voyage. Today, vessels carry ballast that may be fresh, brackish, or salt water (see Box 2-1).

Does a ballast use electricity if no bulbs are present?

No, unlike LEDs, the fluorescent bulb itself (or rather the tube) can not use power when it burns out, however, the ballasts may use a trace of energy whether or not there is a bulb installed.

Do I need an electrician to replace a ballast?

Yes. As a matter of fact, you do need a lock out tag out device in place for changing a ballast. … ‘An electrician is replacing the ballast on a fluorescent light.

Do grow light ballast get hot?

When it’s plugged in, the ballast will send energy through those coils to give you the electricity your bulb needs. All of those components will heat up, and they need lots of constant cooling to keep your lights, plants, and grow room safe from heat and fire damage.

Can you use a grow light bulb in a regular lamp?

Yes. If the regular lamp has the correct socket type and wattage capacity, a grow light bulb should fit into a regular lamp without any problems.

Where do you put the ballast in a grow tent?

If possible, the ballast should be placed outside of the grow tent. Ballasts, particularly magnetic core and coil types, produce heat which is usually best kept out of the tent if possible. Wherever it is located, make sure it is placed on a flat, firm surface such as a table, or hung on a wall.

Will LED bulbs work if ballast is bad?

Can LED lamps work off of existing ballasts? Yes, if they have an internal driver than can work off that ballast. Philips, for example, has designed a tube that is compatible with an existing electronic ballast.

What is the difference between a ballast and a driver?

Fluorescent ballasts provide an initial spike of high voltage, generating an arc that travels from cathode to anode within the discharge tube. … LED drivers convert high voltage, ac current into the low voltage, direct current that LEDs are designed to run on.

Can you bypass a ballast?

Once you have disconnected the ballast from its wires by cutting them, you will be able to successfully separate the ballast from the fixture. You remove the ballast altogether by unscrewing it from the fixture, or you can move it over and tuck it into the fixture with its remaining wires.

What is the difference between grow lights and fluorescent?

Heat Output Of LED vs Fluorescent Grow Lights LED grow lighting puts off next to no heat, whereas fluorescent grow lamps run cool, yet growers do need to consider the heat put out by fluorescent lighting to some degree, particularly with high output T5 fluorescent lighting.

What color of light is best for plants?

  • Violet-blue light in the 400 – 520 nanometer range encourages chlorophyll absorption, photosynthesis, and growth.
  • Red light in the 610 – 720 spectrum range promotes flowering and budding.

Do plants need darkness?

Plants do need that period of darkness for their metabolism to work properly. They are not designed to create food non-stop, and it will do them harm in the long term to put them in this sort of situation. So, yes, plants need their darkness just as much as they need their light.

Can I use LED and HPS together?

Therefore, if you combine the already tested and true HPS luminaires with the more efficient LEDs, plants will be able to take and use wavelengths that they need (when they need them), while also providing radiant heat and diffuse light from the HPS luminaires in addition to being able to extend your light use with …

How much do HPS lights cost to run?

Running this equipment for 16 hours a day (the standard for the vegging stage) means you’ll be using 12.496 KWH a day. With our rate of $. 12/KWH, that puts you at around $1.49 a day for a total of about $44.98 a month.

Can you switch from HPS to LED?

You can expect to save at least 50% on your lighting-related energy costs by switching to LEDs. But it doesn’t end there. LEDs also emit very little heat compared to HPS lamps. When you switch from HPS to LED luminaires, you cut down significantly on supplemental cooling and ventilation.

How much can a 600w HPS yield?

If someone catches you, you only have four plants to your name. Either way, growing four plants using a 600-watt HPS lamp could produce about 150 grams or 5.0 oz per plant. Sixteen plants that are grown under a 600-watt HPS lamp could produce about 37.5 grams or 1.3 oz of marijuana per plant.

What is better for veg MH or HPS?

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.

Do HPS lights get hot?

HPS/MH operate at extremely high temperatures – 30000C/54000F. Much of that heat gets turned into infrared radiation. Infrared is a type of radiation that causes molecules to vibrate and heat up when it hits them. This infrared gets directed down on your plants just like the visible light radiation does.

Can I put a metal halide bulb in a HPS ballast?

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. … Both metal halide bulbs and HPS bulbs are available in medium and mogul base screw in connections.

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.

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.
