LED Dynamics converts T8 fluorescents to LEDs

EverLED LED tube replacements for T8s.

EverLED LED tube replacements for T8s.

Made in Vermont is the sister show of the Vermont Home and Garden Show. In addition to some great foody exhibits, I found this manufacturer of LED lights EverLED. What I liked about this product was the ease of transition from fluorescent to LED. Basically, you pop out your old fluorescent tube and pop in the LED replacement.

This light uses about 40% less energy than a T8, which is the most common tube fluorescent in use today. Like all LEDs it contains no mercury and has no annoying flicker or stroboscopic effect that can happen to fluorescents over time. It also extends the life of the ballast because it doesn’t over heat it. The light output is the same as the T8.

Unlike fluorescents, it is not affected by how many times it is turned on or off during its use, nor does it have a warm-up period.

I spoke with Bob Sparadeo, Sales Directory, who told me that they have been in use for ten years so far, so they are rating them now with a ten-year lifespan, but they really don’t know because they haven’t had one burn out yet.

Colour temperature: The lights are available in three colour temperatures: 3500K, 4000K and 5000K.

They are recyclable at end-of-life.

Suggested applications for this LED light are:

  • Food preparation and service
  • Hard to reach, high maintenance cost areas
  • Clean rooms, laboratories and research environments
  • Museums and galleries
  • Hospitals and medical environments
  • Colleges and universities
  • Office buildings
  • Hotels and hospitality suites
  • Warehouses
  • Parking garages
  • refrigerator and freezer cases
  • retail signs and displays

Measuring Light Intensity with Watts or Lumens — “Watts” the difference? (sorry)

March 11th, 2016

I’ve been meaning to write this post for awhile as the lighting industry is changing over to lumens from Watts to measure light intensity. So, the next time you have to go buy an (LED) light bulb, you will be able to use your newfound knowledge to buy with confidence!

My friends over at Green Builder Media have just published such an article, and they have kindly allowed me to publish it here.

Though an LED bulb may look like an old-fashioned Edison bulb, they are quite different animals.

ONE OF THE MORE EXCITING DEVELOPMENTS in the lighting industry over the past decade has been the emergence of LEDs. The principles of LED lighting have been around for some time, but the real commercial breakthrough of the technology, in terms of both affordable cost and creative applications, has only occurred recently. Though these bulbs may look like an old-fashioned Edison bulb, they are quite different animals, and this new type of illumination works differently than the lighting you are accustomed to.

Kitchen Renovation is Complete — Finally!!

April 8th, 2014
Kitchen renovation

View of kitchen, cabinetry, lighting, maple hardwood flooring

Well, five months after my deadline, my kitchen is finished. I’ve promised my friend Nancy Peterson, CEO of Homestars.com, that I will write a post for her called “Why I will never be my own general contractor again”. Let’s just say it was an eye opening experience. This post, however, is not about the mistakes I made (and there were plenty!), it’s about whether or not I achieved my green kitchen goals.

I would say that I accomplished some green goals but failed miserably in others, in particular with indoor air quality. For many of you, this will be the one area where you will probably not want to compromise. I, on the other hand, seem to be willing to sacrifice mine and my family’s health for the sake of aesthetics, and in some cases, durability.

LED Lighting will surely put me into an early grave

October 29th, 2013

Halo 4″ potlight

I’ve written a lot about LED lighting in the past, mostly because I find that LED lighting is not all that straightforward. Unlike super simple incandescent bulbs, LEDs are really high maintenance….I mean really high maintenance.

I told my electrician I was using LED lighting for the overhead lights and undermount fixtures (not the puck type, but the strip). The task then became what type of LEDs was I going to use? I thought it was simple, but the deeper I dug, the more confusing it all became.

Originally, I had wanted to use Halo 4″ LED potlights at 2700K because I’d seen how they worked in the Nexterra house. I commented that I was surprised they’d used halogen in an “eco-friendly” house and they told me they were LEDs.  The light intensity and colour were an exact match for 50W halogen which was what I was looking for. But for some reason I can’t just settle for the first thing that comes along, I have to research and dig and ask a million and three questions and get myself completely confused before I make a decision.

So I called three different LED lighting vendors and got three completely different answers. Yeesh. The first fellow I spoke with said “Whatever you do, make sure you buy an LED lighting kit. That’s when the bulb and the housing are attached. They are made to work together and will last the longest.”

Then I spoke with another guy who said, “I would never buy an LED kit – what happens if you want to change your lighting? You have to change out the entire kit, not just the bulb.”

Then I spoke to a third guy but he didn’t sell 2700K lights so he couldn’t help me out, although he did try to tell me that 2700K and 3000K colour temperatures are “pretty close.” Believe me, they’re not. I have 3000K LEDs in my living room and they’re a little too ‘daylighty’ for me.

After some hemming and hawing and head spinning I chose the 4″ Halo 2700K pot lights. They are the “kit” kind, which the first fellow recommended (note that I bought them through my electrician, the fellow I spoke with specializes in exterior LED lighting). One reason I decided on them was because I’d seen them in action and liked them. Another reason was because they were reasonably priced — not the cheapest and not the most expensive. I’m just waiting for them now because they have to be shipped from the US. Let’s hope they are as good as I think they are….
