ballast factor led

The best part is that not many manufacturers list this on their sheets and it differs between manufacturers. 0.88 ballast factor; 30-40% energy savings when compared to F40T12 magnetically ballasted systems; Min. There are typically three ballast factors; low (.78), normal (.88) and high (1.2). Old magnetic ballasts won't work with LED lamps. A rule of thumb to know your ballast factor is that interior lights and fixtures are typically at the low or normal factor, while exterior, high bay or garage fixtures are at the high factor. 2931 Lewis Street You will pay a little more in installation, but will have accurate lighting and wattage numbers. Ballast can add as much as 50-60 percent to the wattage of an LED light. Good luck! Please activate JavaScript in order to use this site in full scale. Kennesaw Ga 30144, t: 1-888-871-8139 If the ballast is the same, then you can assume that factor is uniform throughout. The Lighting Gods went into overtime when it comes to LEDs and ballast.

Suite 101 Ballast factor is something the Lighting Gods devised to make sure we must keep using our brains! It is the calculation of the lumen output of a luminaire in combination with a ballast against the reference ballast … Lamps have no regulator and can draw too much or too little power on their own. Many personnel responsible for maintenance and facilities will not have this knowledge. Custom ballast factors … We carry a wide variety of electrical and lighting products. This turnover is lower in corporate facilities and public facilities, but still exists. Here is how we calculate that. One of the most important choices when picking out a ballast for a fluorescent system is the ballast factor.

High Efficiency Systems over 90% efficient, Over 100 LPW (lumens/watt) with OCTRON SUPERSAVER lamps, 30-50% Energy savings when compared to F96T12 magnetic systems, 30-40% energy savings when compared to F40T12 magnetically ballasted systems. If your ballast(s) are magnetic you will either have to replace the ballast with an Instant On Electronic ballast or remove the old ballast(s) and go with direct wire LED … This is important to calculate effective ROI for a lighting retrofit. Find Normal Ballast Factor - Instant Start - 4 Lamp - T8 Ballasts at 1000Bulbs.com. Starting Temp: - -20°F (-29°C) for T8 lamps - 60°F (16°C) for Energy Saving T8 lamps - 0°F (-18°C) … Here’s how the energy usage breaks down for our example fluorescent fixtures: Here’s how the energy usage breaks down for these fluorescent fixtures: 32 W bulb x 2 bulbs x 0.88 (normal ballast factor) = 56.32 … This is important to know as the ballast affects the light output of the lamp it is used with and must be taken into consideration for the deployment and purpose of the light. A ballast's ballast factor can range from 0.70 to 1.20. The formulas above work for fluorescent lighting and ballast, but LEDs are affected completely different by ballast.

With LEDs, that is out the window.

By reducing the ballast factor, it is possible to achieve greater energy savings, meet lumen/foot2 specifications and even qualify for the highest levels of LEED. You must refer to the manufacturer’s “spec sheet” to determine how the ballast factor will affect lumens and wattage. Ballast factor is something the Lighting Gods devised to make sure we must keep using our brains! What is ballast factor? This also affects the energy use.

While I do not recommend checking the 500 fixtures in your parking garage, a spot check of four or five fixtures spread throughout the garage would be a start.

A ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Remember the ratios and calculations used above to determine lumen output and energy use? The same 32-watt tube would only consume 24.96 watts with low ballast factor while also producing less light. For example, a standard T-8 fluorescent tube that is rated at 2,000 lumens would on a low ballast factor produce 1,560 lumens (2,000x .78). Let's say we have a light fixture that has two lamps, and they each emit 2750 lumens. Ballast factor efficiency refers to the actual lumen output for a specific lamp and ballast system as compared to its rated lumen output. In commercial real estate properties, sell and management contracts switch many times over with the engineering staff turning over, too. If you are powering a lamp that emits 1000 lumens with a ballast that has a ballast factor of 0.95, that light fixture will emit 950 lumens. The ballast makes sure that the amount of current being provided to the lamp is not more than the specification of the light.

That is why I always recommend going with Ballast Bypass LEDs vs. Ballast Compatible. © 2020, OSRAM SYLVANIA Inc. All rights reserved. Instant on Electronic ballasts do. Custom ballast factor: Ballast factor is the percentage of light output for a given lamp-ballast combination. Here are our guidelines on choosing ballast factor. Or, commercial ballast lumen output divided by American National Standards Institute (ANSI) standard ballast … In this approach, you multiply the light bulb wattage by the ballast factor. It is the calculation of the lumen output of a luminaire in combination with a ballast against the reference ballast and luminaire when designed and manufactured.
