The Lumatek Digital Ballast is the brightest ballast in the industry. Light meter readings indicate that the Lumatek ballast is up to 27% brighter than common core and coil magnetic ballasts. The Lumatek is 10-15% brighter than other brands of digital ballast on the market.

Over time, core and coil ballasts will degrade, become louder, use more electricity, and produce more heat, while the lumen output declines. Digital ballasts maintain lumen output and efficiency over the life of the unit. The output of magnetic ballasts degrades over time and can fluctuate by up to 10% during a 12 hour cycle. Digital ballasts produce a constant output without any fluctuation.

Magnetic ballasts waste up to 75 watts to convert the electricity, whereas Lumatek sends the FULL 250 watts to the bulb, lighting it to its fullest potential. The Lumatek achieves superior light meter readings in comparison with other digital ballasts on the market through using microprocessors to detect the precise type of lamp used and accordingly supply the correct power. Some lamps are able to use slightly more than 250 watts. The Lumatek ballast will detect this difference and increase output accordingly.

Electronic Ballast vs E-Ballast
The Lumatek ballast is an E-ballast, unlike other brands on the market, which are actually electronic ballasts. E-ballasts use a microprocessor similar to a component found in a personal computer. This microprocessor allows the E-ballast to run either halide or sodium lamps, to switch between 50 and 60 hertz, to make adjustments for the type of bulb it is running, and even to compensate for degraded lamps by increasing its output. Electronic ballasts have a constant output and cannot make adjustments or changes. They will light a MH lamp; but quickly cause it to degrade, thus shortening the lamp`s lifespan.

Lumatek ballasts are programmed to allow for a `soft start` and do not require an initial power surge to start the ballast. This allows end users to start multiple ballasts simultaneously without blowing a breaker. The ballast will also detect a short in the wiring or a defective lamp. It simply shuts itself off, letting the user know that something is wrong. This should be kept in mind if you have a customer whose ballast keeps shutting down. In most cases, there is a problem with the output wiring.

Surface Temperatures
All digital ballasts produce the same amount of heat due to the total heat output. Do not be fooled by inferior units that use fans. These fans do not make the units run cooler. They simply exhaust the heat into the room. Each unit is tested at the factory for 12 hours with the lamp 6 inches from the unit. We are currently testing a new Mosfet that will lower the running temperature of the 120v unit. The Mosfet is the power supply circuit. It transforms the input electricity to the correct current and voltage for the ballast. This is the most important part of the electronic ballast and makes a huge performance difference.

Warranty Information
Lumatek offers the best warranty in the industry, 3 - year replacement and 2 - year pro-rated. Lumatek will replace any defective units with brand new units for 3 years from the date of purchase. Please retain the original receipt from the place of purchase. A copy is required for all warranty issues. Also, these units should not have been modified or physically damaged. During the fourth and fifth year, Lumatek will supply the customer a pro-rated replacement ballast. For warranty issues, call the toll free support line 1-866-369-8943.

Market Confusion

There are several Lumatek look-alikes on the market. Do not assume that these have the same exclusive quantity and performance as the Lumatek. They typically use inferior components and technology and are not true E-ballasts.

The Lumatek Ballast is the brightest in the industry. Light meter readings indicate the Lumatek is up to 27% brighter than common magnetic ballasts and 10 - 15% brighter than competing electronic ballasts. Over time, magnetic ballasts degrade, become louder, use more electricity, and produce more heat, while the lumen output declines. Digital ballasts do not degrade and maintain their lumen output and efficiency over the life of the unit.

The Lumatek is not just your standard electronic ballast, but is a more advanced E-Ballast. What is the difference? E-Ballasts use a micro-processor similar to your home computer. This micro-processor allows the E-Ballast to run halide or sodium lamps, make adjustments based on the type of lamp it is running, and will even compensate for degrading lamps by increasing output. Electronic ballasts have a constant output and cannot make adjustments or changes. There are plenty of other digital ballasts on the market, do not assume they are all the same. Typically they use inferior components and are not true E-Ballasts.

The Lumatek is programmed for a `soft-start` and does not require an initial surge of power to light the lamp. This increases the lamp life and allows the end user to start multiple ballasts at the same time without tripping breakers. To ensure safe operation, the Lumatek is programmed to automatically shut off in case of a short in wiring or a faulty or missing lamp.

Manufacturer Info

The best Electronic Ballasts money can buy...
More power, more lumens more blooms......

Lumatek is the worlds leading supplier of Electronic Ballasts to horticulture. With the arrival of Electronic Ballasts, a technological revolution has taken place in energy efficiency for HID lighting. This replacement of magnetic ballasts (a technology more than 100 years old) with electronic HID ballasts is because of the proven efficiency gains. Tests have shown that Lumatek ballasts are up to 30% brighter than some old style magnetic ballasts. Independent laboratory tests have proven that Lumatek ballasts are more efficient than any magnetic ballast known to Lumatek. This means more lumens are produced per watt of energy consumed.

Lumatek is the number one supplier of Electronic Ballast to the hydroponics and horticultural industries worldwide, and is proudly available in at least 13 countries. Lumatek products are sold into government research facilities, major nurseries, top universities and numerous publicly traded companies. This makes the Lumatek range the most proven product in the market, in addition we have the industries best warranty with 5 years covered (3 years full and two years pro-rated).

Beyond my expectations

REVIEW
For the last 14 years, I have run 8-400 watt MH bulbs on a 1200 gallon reef tank. I have used many brands and types ballasts. I am pleasantly surprised with the performance of the Lumatek ballasts. The bulbs start softer and burn significantly brighter. I also notice an improvement in the color of...Read More

Good, but...

REVIEW
Ballast works well, starts up quickly, but the "super lumens" setting doesn't seem to do anything. Instructions don't mention if you have to restart the ballast to switch to "super Lumens" mode. Also, the rubber feet fall off easily. Instructions are basically just a marketing fl...Read More

Absoulety Magic

REVIEW
The beautiful purple brushed finish is enough to warrant buying this ballast. The fact that it magically transforms any ho-hum aquarium into an awe-inspiring shimmering reef is merely a secondary reason to buy it. Highly recommended. Oh... don't forget to get some heat rated wire nuts for your pe...Read More

This is a high quality product that meets all expectations for light output and surprisingly low heat generation (energy efficiency). I am very please with the overall quality of the unit, especially the integrated aluminum case/heat sink, light weight, and compact size. I retrofitted a Coralife m...Read More
