3 Easy Steps: Pick the Right LED Retrofit Kit vs HID / HPS

How do you choose the right LED model to retrofit HID fixtures?  How do you know X watt of LED really equals 400 watt of HID?  You need to spec the right wattage, the right product, every time.  Follow these easy steps to spec the right product every time and close more projects faster with each decision maker.

LED Retrofit Kit

LED retrofit kits replace HID and HPS lamps, but how do you chose the right model?

3 Simple Steps to Compare & Spec LED to HID Metal Halide

  1. Mean lumens of HID* x Efficiency of Fixture** = Effective Lumens
  2. Match HID fixture effective lumens with LED retrofit kit or fixture
  3. Select the matching LED retrofit kit and quote your customer

3 Simple Steps to Compare & Spec LED to HPS High Pressure Sodium

  1. Mean lumens of HPS* x Efficiency of Fixture** x 0.38 for perceived lumens = Effective (Perceived) Lumens
  2. Match HPS fixture effective lumens with LED retrofit kit or fixture
  3. Select the matching LED retrofit kit and quote your customer

Example: 250 Watt HID high bay project

250W HID = 21,250lm x 0.65 (mean lumen calculation) x 0.65 fixture efficiency = 8,978 effective lumens per fixture

Our 80 Watt LED Retrofit Kit matches perfectly to replace this 250W HID for this example.

Note: Mean lumens vary per manufacturer and each fixture has a unique efficiency value.  While many people use somewhere between .6~.7 efficiency for high bays and .65 to .7 for shoebox fixtures – much higher efficiency reflectors exist.  The above is only an example and exact data is available with each respective fixture.

For many lighting projects, specking the right LED retrofit solution replacing metal halide HID is this simple.  For more detailed comparisons, Green Lighting LED has IES files and can run photometric layouts as a free service for any energy saving project.

Top 5 Things You Seriously Didn’t Know About LEDs

Today, we’re doing a Friday countdown of 5 things you probably, seriously, did NOT know about LED light bulbs and LED lighting technology.  How many out of the 5 did you know about?  We hope you learn a little something about our passion and have a fun time with this post.  We did!

5Light Emitting Diodes have been around over 50 years!  GE’s employee Nick Holonyak produced the first visibly red LED back in the early 1960s.    Within the next few years, diodes got brighter and yellow diodes came on the scene.  By the 70s, red diodes were hot items commercially, showing up as indicator lights and even in some calculators.  While the LEDs weren’t ready to show up as a light bulb yet, they were being used in many electronic devices.  They’re in your old radio, TV, and digital clock.  Oh, and did you know people in LED suits run around Bangkok?

4 – Sorry, we’ll try to stay on topic! Someday, you will paint your LED lights onto your ceiling!  This technology, called OLEDs, someday will replace the light bulb.  It works by having a polymer plastic layer emit light when an electric current passes through.  Imagine your ceiling being your lighting source lighting up and dimming down with the sun.  Imagine the newspaper being an electronic plastic sleeve, or your cell phone being as thin as a sheet of paper, or your wall paper lighting up in the evening at the dinner table.  To better understand some of the potential with OLED lighting, check out this video!

3 – Lots of manufacturers make false claims about their LED light bulbs!  Buyer beware.  25,000 hours, 50,000 hours 100,000 hours is just a number, but if the product doesn’t have the right components – your LED bulb or fixture won’t last.  We recommend only working with Lighting Facts and Energy Star partners, who have the data to support their claims.  Also, watch out for the warranty.  Is your warranty a full replacement warranty or a limited warranty.  The number of years on the warranty is less valuable than the company’s willingness to support a claim.  Read the fine print and know you probably get what you pay for…

2 …LEDs are a lot less expensive than you think!  Typically, customer’s return on investment happens in two years, even less where electrical costs are high.  Think about where you could start saving by switching to energy efficient lighting technologies.  Without any mercury or heavy metals, Green Lighting LED’s look and perform like a standard product, but provide the energy savings and long life of LED lighting technology.

1 One LED light bulb, the LEDshine360, actually looks like a regular light bulb!  Most LED bulbs on the market look like they just arrived from outer space.  Phillip’s LED light bulb looks like a mushroom.  GE’s LED light bulb has a massive claw working around the edges.  Even Cree’s new light bulb looks like a hot air balloon crashed into a flying saucer.  Green Lighting LED dared to imagine a light bulb you could run over with a truck, while looking exactly like a light bulb should.  Our patented LEDshine360 looks like a light bulb and performs like an LED.  It’s tomorrow’s light bulb, shaped like yesterday’s.

Happy Friday everyone!  We hope you enjoyed our Top 5 Things You Didn’t Know About LEDs countdown.  Let us know what we missed!  Now, enjoy us running over a light bulb with our truck.
