The Cost-Cutting Power of eHID Technology

Electronic HID (eHID) ballast technology is a cost-cutting innovation that is shaking up the lighting industry by providing significant energy savings compared to standard magnetic HID ballasts. Electronic HID ballasts allow precise control of light output while using less electricity, enabling a reduction in lumen depreciation and energy consumption, in addition to savings achieved through lowered maintenance costs. The design of the ballast combines all the best elements of traditional HID systems integrated into a single, compact unit with improved ignition technology that improves the lifespan of the lamp and ballast. While fixtures equipped with eHID ballasts and approved lamps may cost more initially, customers will save significantly with reduced energy and lower maintenance as well.


When paired in luminaires with Metrolight-approved lamps, the potential savings are significant. Replacing aging lighting with eHID technology will typically provide over a 50% reduction in energy consumption without sacrificing lumen output or color quality. These light fixtures can replace traditional metal halide fixtures between 100 and 1000 watts with remarkable results. For example, a 1000w metal halide fixture can be replaced with a 450w eHID light fixture and provide as much light and longer life, along with all of the additional savings associated with the conversion.


This fixture is a 450 watt eHID Pulse Start – Metal Halide Premium Tilt Large Flood Light with Type 5 Reflector. It will provide as much light as its 1000w magnetic ballast equivalent. This fixture can be purchased from Access Fixtures here.


By providing a substantial reduction in energy consumption, improved lumen maintenance, precise dimming capabilities, and improved efficiency over magnetic HID ballasts, Metrolight-powered eHID fixtures are ideal for virtually any HID application. The dimming capabilities of these ballasts extend lamp life and dramatically reduce the frequency of lamp replacement, lowering maintenance costs throughout the life cycle of the lamp and ballast. Electronic HID ballasts can be connected to a number of standard control devices including analog and digital dimmers, sensors, and timers. This allows for dimming that can be controlled to accommodate human activity, daylight harvesting, and interactive light systems, all of which provide significant additional energy savings. Additionally, eHID technology will likely qualify your facility for rebates from your local government or utilities provider, further offsetting initial replacement costs. Electronic ballasts exceed the requirements of the Energy Independence and Security Act of 2007, which regulates ballast efficiencies for metal halide lamps. Electronic HID ballasted fixtures may also qualify for rebates from local utility companies, further offsetting initial replacement costs.

Lightfair 2012 is ON!

Welcome to Lightfair International my fellow lighting enthusiasts. I look forward to this momentous and vibrant occasion every year. This year’s Lightfair convention is located in Las Vegas Nevada, a place that is already so overwhelmed with bright and exciting lights, that I already feel like I’ve died and gone to heaven.

Over the next few days I will be breaking a major rule. A Vegas faux pas if you will. They say that ‘What happens in Vegas stays in Vegas’; but I simply can’t resist. I will be updating everyone with some of the brightest and best new lighting products that will be coming out this year! Recent trends in LED and solid-state lighting have pushed lighting innovation harder than ever, hopefully resulting in some new and beautiful fixtures!

First up we have emergency lighting and exit signs!


For the first time ever, exit signs with emergency lighting has gone 100% LED! In the past, a few LED’s illuminated the lit area behind the EXIT letters while the emergency floodlights were halogen. This implementation of LEDs is further reducing energy costs, and eliminates the need for replacing lamps and checking the battery backup.  This new series of high performance full LED exit signs will be available soon. See a feel line of EXIT lighting here!

My Favorite Light Bulb – The Sun


George Harrison and the Beatles had it right when they wrote the song “Here Comes the Sun” back in the late 60’s. As much as I love light bulbs, nothing beats our big bright sun. Now that winter is winding down, we can all look forward to having longer and warmer days with a lot more sun! 

The sun is arguably Earth’s light bulb. On top of the sun’s impressive lifetime, beautiful CRI, and zero lumen depreciation, it has benefits that no light bulb can come close to. For instance the sun provides us all with the Vitamin D. 

Get out your shoes/sandals and head outside for exercise and plenty of Vitamin D! Vitamin D is a nutrient that supports the absorption of calcium and it also supports breast, colon and prostate health, while contributing to the maintenance of a healthy mood. So while you are outside, you will be happier and healthier.

So what happens when the sun goes down? This question was answered best by my man Thomas Edison back in the 1870’s with the invention of the first electric light bulb. It’s been over 140 years since the dawn of light after dark – and A LOT has changed. We have gone from inefficient incandescent bulbs, to highly efficient solid state LED fixtures capable of lighting our sports fields and major roadways. Humans have truly become reliant on these miniature artificial suns that allow us to live comfortably even when dusk has come and gone.  

Although our lighting technology can’t give us the vitamin D our bodies need, our new lighting technology has made it possible to enrich our selves in different ways. For instance, without artificial lighting, colleges could not have the ability to teach students in night classes. Cars would not be able to safely drive after sunset. The list goes on!

After the sun has set, anything is possible with the right lighting. If you want to light your tennis court to continue lessons and match play into the evening… No Problem. If you want to keep your buildings parking garage safe for employees leaving after dark… No Problem… If you want to grow fruits and veggies year round in your basement… NO PROBLEM. Lighting for commercial and residential applications has never been so efficient and visually effective.


Why Don’t You Have LEDs Yet?

Its 2012 and in another two years you wont be able to find incandescent lamps anymore. That’s right folks; the traditional soft white lamps you have in your kitchen or hanging in your restaurant will no longer be easily available. So what will we do and what is the future of lighting?

If you haven’t heard it from someone else you are hearing it now from Dr. Bulb: LED and solid state lighting is the future. They are durable and small enough to fit on a key chain, they last for close to a decade, and they are extremely energy efficient. The movement away from incandescent to LED is occurring, but it is happening slower and more painfully than VCs or entrepreneurs expected.


With LED technology, you change lamps less, experience less lumen depreciation, and save massive amounts on your energy bill. So what is keeping people from this new technology?    

Unfortunately, LEDs have not yet made it into the home on a large scale. However, they have started to make it into the enterprise. Groom Energy and Greentech Media Research predict that the LED enterprise lighting market will grow by 30 percent in 2011 and surpass $1 billion in annual revenue by 2014. The 2010 U.S. market for commercial and industrial LED lighting is sized at $330 million in annual revenue. 

The initial cost of LED lighting doesn’t help the cause, either: light bulbs show tremendous price elasticity. This means that small changes in the price will have a much larger effect on the demand.

Fred Maxik, the founder and CTO of the 900-employee Lighting Science Group, doesn’t feel that cost is holding the industry back. He said recently that in commercial and retail applications, LEDs can today be justified on an energy efficiency basis. What’s needed, according to Maxik, is consumer education. More consumers and business owners need to understand the benefits of this technology and spread the good word.

Where are the LED evangelists? Why are there not people shouting from the rooftops that they reduced their home energy costs by hundreds of dollars. Here at my Dr. Bulb headquarters, I just installed a bunch of new >Kumho LED lamps in various fixtures as well as my track lighting system. These are currently available on Amazon.  Adopting a new lighting technology shouldn’t be that hard. Not only am I saving big on my monthly energy costs, but I have some of the most high tech and lamps available in the lighting industry. Jealous? Get your own today and let the saving begin!

Induction Lamps Brighten Up The University of Michigan’s Player Development Center

The University of Michigan’s men’s basketball team is shooting for a Big Ten title and a long NCAA Tournament run this season. While the Wolverines continue to rack up victories in games, brand new induction lighting is helping them on the practice court.

Fifty-six Induction High Bay fixtures were installed in the university’s state-of-the-art Player Development Center, which is attached to the arena where Michigan plays its home games. Induction is a perfect fit for gymnasiums and recreation centers   


Induction technology is basically fluorescent lamp lighting without electrodes. It uses magnetic induction to ignite the phosphors instead of electrodes. The main advantages of induction technology are as follows. Electrodes are a significant point of failure on traditional fluorescent lamps causing more frequent replacement. Induction lamps do not have electrodes and consequently have an extremely long life, rated at 100,000 hours. Also, the lack of electrodes makes them more reliable in high-vibration applications such as gymnasiums and fitness centers. The second major advantage is the ability to use light generating substances that would react with metal electrodes in normal lamps, enabling the use of higher performance substances for more light.

 Induction lights are ‘instant-on.’ A coach can flip a switch and start practice instead of waiting several minutes for them to warm up and fully illuminate.

Induction technology delivers an unequaled 100,000 hours of high quality white light which makes them virtually maintenance free. That is the equivalent of 100 incandescent lamps, 5 HID lamps, or 5 typical fluorescent lamp life cycles.

Induction Lighting v. LED and Other Lighting Technologies

While the current buzz in the press is LEDs and LEDs will someday become a significant technology in luminaires, for now LEDs are not the end all – be all, and they will not be the solution for everything.  There are many lighting technologies that are still significantly more energy efficient, last longer, or are a better light technology for a specific application.  An example is Induction Lighting. Induction light fixtures perform for up to 100,000 hours making them virtually maintenance free, provide high color rendering (CRI) , have minimal lumen depreciation over the life of the lamp, and very energy efficiency too,


Induction Wall Pack

The inherent benefits of Induction light fixtures make them ideally suited for applications such as difficult to access locations, expensive to access locations, and areas with vibration and places where long term reliability and energy efficiency are valued.  As compared with LEDs, LED light fixtures are just beginning to have enough light output to be used in place of traditional high intensity discharge light sources.  The cost is very high, and compared to induction lighting, LEDs have half the rated light.  Additionally, LEDs are sensitive to temperature.   As the temperature increases, light output of LEDs decreases and the life of the LED luminaire is diminished.  Heat has virtually no impact on the light output of an induction system and in a properly designed fixture has zero impact on system life too.

The U.S. Department of Energy on one of their Energy Savings Blog reports, “Induction lighting is one of the best kept secrets in energy-efficient lighting. Simply stated, induction lighting is essentially a fluorescent light without electrodes or filaments, the items that frequently cause other bulbs to burn out quickly. Thus, many induction lighting units have an extremely long life of up to 100,000 hours. To put this in perspective, an induction lighting system lasting 100,000 hours will last more than 11 years in continuous 24/7 operation, and 25 years if operated 10 hours a day.”


Induction High Bay Fixture Shown with Optional Acrylic Refractor

An example of an application where Induction lighting is a superior choice as compared to other lighting is an industrial manufacturing setting that is operational 24/7.  Since heat rises, typically it is very hot near the ceiling/roof, which is not good for the life or light output of LED luminaires.  Also, LED luminaires are expensive and most can’t put out enough light. Linear fluorescent high bay fixtures require clean reflectors and are susceptible to dulling in areas with chemical processes.  Also the lamps get dirty and consequently put out less lumens. High Pressure Sodium is efficient but the color rendering is about 20 which is not sufficient in some production areas and is strongly disliked by workers. Metal Halide is a great high bay light system, but does not have the life, lumen maintenance, or in some instances the energy efficiency of Induction lighting.

In summary, there is a best solution if one understands the tradeoffs.  Each lighting source has its place.  In the case of Induction lighting, it has tremendous merits, but comes at an initial cost that is higher than most other lighting technologies.
