Most grow lights need a ballast. … The best way to do this is to get an HID grow light kit that includes everything you need (MH bulb, HPS bulb, ballast, reflector, hangers and timer), but if you already have some of those components, you can get the ballast on its own.
Can I 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.
When should HPS ballast be replaced?
HPS bulbs should last four to six years, depending on the number of on/off cycles and hours of use. The second most common failure is the capacitor. If screwing in a new bulb does not solve the problem, the lamp must be taken down and disassembled. If the capacitor is enlarged, it has failed and needs replacement.
What does a ballast do in a HPS light?
The temperature of the vapor is controlled by the power supplied to the lamp. With higher power comes higher temperatures and thus higher pressure in the tube, which creates more light. The ballast is an inductive ballast that helps regulate this power by keeping the current constant, instead of the voltage.How long does a HPS ballast last?
These devices usually run on a 220V AC electric supply at 50-60 Hz Frequency. According to the Certified Ballast Manufacturers Association, the average Magnetic ballast lasts about 75,000 hours or 12 to 15 years with regular use. In contrast, the Electronic ballast can last up to 20 years.
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.
Why is HPS better for flowering?
The higher lumen or light intensity is also gotten from high-pressure sodium lights. The intensity is usually 25 to 40 percent greater than metal halide bulbs or even the same wattage. This is why HPS is better for flowering because the more light the better for the flowering plant results.
Why do you need a ballast for lights?
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.Do all grow lights need a ballast?
Most grow lights need a ballast. With fluorescent lights the ballast is built-in and LED lights don’t need one. But if you’re thinking of going with HID plant lights, you’ll have to buy the ballast separately.
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.
Article first time published onHow long do ballasts last?
According to the Certified Ballast Manufacturers Association, the average magnetic ballast lasts about 75,000 hours, or 12 to 15 years with normal use. The optimum economic life of a fluorescent lighting system with magnetic ballasts is usually about 15 years.
How do you tell when my HPS bulbs are done?
My little joke at the beginning actually holds true: the easiest way to tell if an HPS bulb is burnt out is to put it in a fixture and see if it turns on. Apart from that, you can usually see some burning inside the bulb, around the inner tube.
How do you test an HPS ballast?
- Step 1 – Remove the Lamp. …
- Step 2 – Visually Inspect the Lamp. …
- Step 3 – Check Accessories. …
- Step 4 – Test the Voltage. …
- Step 5 – Check the Ballast. …
- Step 6 – Check the Short-circuit Current.
What causes a ballast to fail?
Causes of Ballast Failure Premature ballast failure is often caused by the surrounding environment. … When it’s too hot or too cold, the ballast can burn or fail to start your lamps at all. Heat combined with prolonged condensation inside an electronic ballast can cause corrosion.
Do digital ballasts use less electricity?
Energy Saving Digital ballasts are waaaaay more efficient. It’ll vary, depending on which units you compare, but typically digital ballasts use 3 – 4% less energy. This doesn’t sound like much but, when you’ve got multiple grow lights on the go, the combined saving really cuts down your energy bills.
What are the signs of a bad ballast?
- Buzzing. If you hear a strange sound coming from your bulbs or light fixture, like a buzzing or humming noise, that’s often a sign your ballast is going. …
- Dimming or flickering. …
- No lights at all. …
- Changing colors. …
- Swollen casing. …
- Burn marks. …
- Water damage. …
- Leaking oil.
Can you use HPS for the whole grow?
While either type can be used for the full growing cycle, when combined, using an MH grow light for vegetative growth and flowering under an HPS grow light is the most recommended HID grow light setup because utilizing the strengths of both types at the right times produces the best results.
Can you veg and flower with 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.
How much heat do HPS lights produce?
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.
Can I switching from HPS to LED during flowering?
LEDs Provide a Higher Quality Light Spectrum There was a time when switching from MH to HPS bulbs between veg and flower counted as tailoring your light spectrum to your plants’ needs. … When you switch from HPS to LED, your plants receive the blue hues they need for sturdy growth and root development.
What is the advantage of HPS?
Advantages. Most efficient member of the HID light family, 7 times as efficient as incandescent and over 2 times as efficient as mercury vapor. Warm-up period is 3-4 minutes, which is somewhat less than that of a mercury vapor or metal halide lamp. Long lamp life — 24,000 hours.
What yields more HPS or LEDs?
Higher Yields A 600w HPS light can produce up to 150 to 300 grams in optimal growing environments, which is 0.5 grams per watt or less. LEDs, however, can produce as high as 1 to 1.5 grams per watt. All the while, LEDs use less energy to produce the equivalent HPS wattage.
How do I know if my light has a ballast?
You can determine whether you have a compatible fixture in seconds. Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.
Do Recessed lights have ballasts?
Types of Recessed Light Fixtures They do not use a transformer, ballast, or driver, which makes them inexpensive and the most trouble-free. Low Voltage (12V or 24V) – Most often used for accent lighting. Their compact lamps allow for a wide variety of adjustable trim options.
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.
Will ballast compatible LED tubes work without a ballast?
If the LED tube is not compatible with your ballast, you would then need to replace your ballast in addition to the T8 LED tube. … The T8 LED tube won’t work without the ballast, so you are forced to continue buying and replacing ballasts as long as you have an LED tube that is ONLY ballast dependent.
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.
How is ballast pronounced?
Break ‘ballast’ down into sounds: [BAL] + [UHST] – say it out loud and exaggerate the sounds until you can consistently produce them.
Do Type A LED tubes need a ballast?
Type A LED tubes need an existing T8 electronic ballast to operate. If you have T8 electronic ballasts this makes installation very easy.
Why are my fluorescent lights flickering?
If your fluorescent bulbs flicker, most likely the problem is with the bulb itself. If the bulb is very dark on either end, it may be defective and burned out. The best way to test the functionality of a bulb is to put it into a fixture you know works. … Flickering fluorescent lights can also be a result of temperature.
How much does ballast cost?
A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably – for about 5 minutes work on each light fixture.
