LED Corn Lights

LED replacement lamps often referred to as corn lights because of their rows of led chips are one of today’s most efficient ways to replace metal halide, high pressure sodium and mercury vapor light bulbs.  LED Corn lights last longer that all three high intensity discharge lamps, currently the standard life is now 50,000 hours allowing for considerable less maintenance requirements allowing for even greater savings.  These are available in a wide range of lumen outputs, replacement wattages start as low as 16 watts and go as high as 450 watt that’s covers all high intensity discharge wattages between 35 and 1500 watts.  Another benefit of the LED Corn lights is their ability to maintain their bright light throughout their lifespan, as much as 80% of the lumen out will remain throughout the life of the lamp.

Base Type.  These lights come in two different bases, Medium E26 which is your standard household size base and the E39 Mogul base that all the higher wattages come in.    

Color Choices.  LED Corn lights are available in a wide range of colors.  Starting at 3,000K and increasing all the way up to 5,500K.  The warmer 3000K will do a good job of simulating the warm High Pressure Sodium lights and consider 5000K for any warehouse, parking or security lighting.  If you are unsure what light will work best for your application please give one of our lighting designers a call to make sure your getting the correct color for your application.

Return On Investment.  Typical return on investment can be as low as six months depending on what you pay per kilowatt, how much wattage you were using and what the replacement wattage will be.  

Rebate Incentives.  Many utility companies now see the benefit in switching out the High Intensity Discharge lights and you may be able to receive a portion or all of the cost to make the switch.  To find out more contact your local utility company, we have a helpful Utility Rebate section to help locate rebates in your area. 

Troubleshooting

With a large surge of manufactures looking to gain market share in this growing category there are numerous issues to avoid.  Before choosing an LED Corn Light consider a few things first.

1.  Wattage

Is the wattage listed actually sufficient to replace the current HID lamp.  It has become common place to have a wide range of LED wattages available for the same HID lamp.  Manufacturers do this to attract more buyers by appearing to reduce the replacement cost, example...  Typically replacement wattage for a Metal Halide MH400 lamps should be 120 and at the lowest 100 watt depending on the LED Corn Light lumens per watt rating.  Many manufacturers will list a wattage as low as 60 watt to replace a 400 watt metal halide, well below the needed light level.

2.  Size

One of the main issues customers run into is the recommended LED replacement corn light is too large to work with their current HID application. There are a few workarounds for this issue, a few manufactures have addressed this by making reduced size LED corn lights that were designed to fit into these tight applications and work in enclosed fixtures. 

3.  Heat

The majority of issues like blinking, partial or complete failure are due to overheating.  It is critical that the LED corn light you choose is not so tight in the fixture that the application doesn’t create too much heat and causes an issue.  If you’re unsure about your application please give us a call and we can review your fixture and recommend the perfect replacement.

4. Direct Wire or Ballast Compatible

The overwhelming majority of the LED Corn Lights work without the ballast.  Although there are LED Corn Lights that work with the ballast it is not common and avoid damaging the lamp by making sure the light you are installing is ballast compatible or not.  If you are installing the LED corn light and it is the direct wire version you simply have to remove the HID Lamp, remove the HID ballast and wire the power directly to the socket.

BEST RETROFIT LED BULBS TO USE IN METAL HALIDE LIGHT FIXTURES

Metal halide lamps have long been the standard for high-wattage lighting applications. Thanks to their high lumen to watt ratio, they have been the industry standard for outdoor, industrial, and commercial lighting for decades. They are limited, however, by a steep dropoff in efficiency as they age. Until recently, frequent replacement or additional metal halide fixtures have been the only options to maintain peak lighting as bulbs age, but LED bulbs are fast becoming a better solution.

WHERE HAVE LED BULBS BEEN HIDING?

By finding the best LED replacement for your metal halide fixture, you can get a high level of illumination using less wattage and lowering your utility bills. Light-emitting diode (LED) technology advancements now allow you to retrofit your metal halide lamps with a simple bulb change. LEDs can give you comparable lumens at a fraction of the energy cost. They are also longer-lived and show a lower reduction of performance over their service life. While the initial bulb purchase can be more expensive, the cost differential is more than made up for in savings over the life of the bulb.

WHICH BULBS SHOULD I USE?

When choosing the best LED replacement for metal halide fixtures, you will want to decide whether or not you want to remove the ballast and operate the bulb on direct line voltage 120-208-220-240 or 277v, or if you want to operate the bulb directly on the existing metal halide ballast. In the latter case, you want to make sure your bulb offers comparable lumens first and foremost. Remember, metal halide bulbs degrade relatively quickly and lighting systems are designed to take that into consideration, as should you when selecting your LED bulbs.

Corn cob and metal halide bulb comparison

Metal halide fixtures are used commonly in post top lights, street lights and in warehouse high bay fixtures. In some instances, it is a great idea to  retrofit your metal halide bulb with an LED retrofit option. Our team of experts can help you decide whether or not your fixture was designed to allow some heat dissipation as the heat build-up in a fixture can drastically shorten the life of the best LED bulb.

If you are going to do away with the ballast and run direct voltage to the lamp, you’ll want to find a bulb that has a smart voltage sensing system. Typically you will see the bulb is rated for 120-277V. This means it will operate on any voltage between 120 or 277V. For this type of retrofit, we suggest an electrician come in and dismantle your fixture and bypass, and/or remove the old metal halide ballast and run direct voltage to your socket. Sockets can be medium E26 base or mogul E39 or EX39 so check your sockets to make sure you get the right one.

LED corn cobThe most common variety of ballast bypass LED metal halide fixture replacement is what we call LED corn cobs. They come in mogul or medium base, and only the mogul-based lamps are DLC approved for applying for rebates. These bulbs have multiple chips and are shaped like a tube so that they fit where the old bulb was. Verify beforehand that your new LED retrofit bulb will fit inside the fixture. In many instances, the equivalent LED option is bigger than the metal halide bulb that came out of the fixture.

Some of these bulbs have a 5Kv to 6Kv surge suppression system built into them and others like Keystone Lighting, Philips and Halco come with an additional surge protection This unit goes inline with the power as a separate unit to protect your new investment from power surges, lightning strikes and other acts of God that are not covered under the factory warranty. These are great replacements for post top lights, wall packs and recessed can lights.

The other option is to run your new LED on the existing metal halide fixture. With this technology, it is truly a plug and play switch. There is no need to update the wiring or to change anything with your existing fixture. In this application, the biggest thing is to make sure you know what ballast you are operating so you can match up the correct LED plug and play metal halide replacement bulb to the ballast.

All ballasts have an ANSI code on them. The codes for metal halides start with an “M”; once you find this you will see 2 or 3 numerical digits like “M59”. This tells you that you have a 400w metal halide probe start ballast. If you had a warehouse with a high bay fixture in it, you might find these ballast and bulbs. They were very commonly used in the ‘70s, ’80s, and ‘90s in commercial applications, such as metal halide fixture warehouse high bay lighting.

WHAT’S IN A NAME?

To ensure you’re getting the best LED bulbs for replacing your metal halide lamps, you’ll want to use a supplier that can give you brand name LED bulbs. There are plenty of manufacturers rushing to join this growing segment of the lighting industry, but their products may not stand the test of time.

Brands such as Philips, Keystone Lighting Technologies, Olympia Lighting, Halco and Eiko have put in the blood, sweat, tears, and years to push LED technology forward for commercial application. By choosing a trusted brand, you are ensuring you get a quality product manufactured to the industry’s most stringent standards.
