Susan LED Upgrade for Warehouses with 400W Metal Halide

Thinking about switching to LED can be a very big decision. How about a plug-and-play lamp that makes installation safe, fast and easy!

The decision to upgrade to energy efficient LED lighting makes perfect sense on paper but the installation, rewiring and down time of the retrofit can affect your decision.

The return on investment can be huge, improved light levels makes for safer working environments and the maintenance savings are unbelievable.

So why isn’t every warehouse in Atlanta lined up at our door to purchase LED lighting for their warehouse?

Here is why…

The task can seem daunting for a facility manager or for the pocket book of a CFO. It is usually just easier to put it off until next year and buy another 6 pack of those energy sucking, inefficient 400W metal halide bulbs and just go about our day.

But wait! Let’s check out how easy it really is to go from metal halide to LED by using the Lunera Susan LED plug & play replacement lamp. It is so easy you will be amazed. Simply unscrew the old metal halide lamp and screw in the new LED lamp.

Viola. Your done!

Let’s find out what kind of metal halide system you have. You will need to identify the type system in play by checking the part number on the existing bulb. To do so, turn off the power. Wait 15-20 minutes for the 400W metal halide bulb to cool down. Once cooled down you will need to use a lift or ladder to safely gain access to the fixture. Unscrew the lamp and look for the part number etched on the glass. If it is a 400W or 320W bulb you will be able to use the Susan SN-V-E39-400W-320W-5000-G2.

To verify what system we have we need to find the “M code”. The M code is the ANSI ballast designation for the lamp. If it says M59, M59/E, M59/O, M132, M135/E, M135/O, M155, M155/O, M155/E we can use the referenced model above.  Atlanta Light Bulbs offers 2 options for 400W metal halide high bay fixtures. The 4000K cool white version SN-V-E39-400W-320W-4000-G2 or the crisp white light of the 5000K version SN-V-400W-320W-5000-G2.

Both versions are also offered with the up light option(just add U after the V) for prismatic clear lensed fixtures, they allow some up light to escape from the back side of the reflector so the fixture presents its traditional “glowing” effect. Next, simply purchase your Lunera LED replacement in 5000K(my personal favorite) from by clicking here.

In this scenario, I was retrofitting a 400W metal halide pulse start M135/E high bay demo fixture we have hanging in our warehouse.

The power was already off and the lamp was already removed from the fixture. At this point we have done all the major work.

Now all we need to do is to screw in our new Susan LED 400W metal halide replacement lamp!

Once the lamp is tightly screwed into the socket you will need to secure the lamp with the wire and hook system. This secures the lamp.

Remember their is no need to touch the ballast or do any rewiring!

Turn on the power and enjoy the benefits of higher light levels, instant on light(no warm up time like with metal halide), reduced power consumption that yeilds a 60-80% energy savings!

Lunera’s BallastLED technology makes these lamps truly plug-and-play by allowing them to operate directly off of existing ballasts. Simply replace the existing MH lamp with the Susan Lamp without making any modifications to the fixture.

The Susan Lamp has a rated life of 50,000 hours – 5 times longer than that of MH lamps. This eliminates costly replacement cycles and reduces maintenance costs.

The Susan Lamp is available in a range of color temperatures including 3500K, 4000K and 5000K. It delivers consistent light levels across its long life, which results in a high quality lighting experience for the building’s occupants.
