The ABCs of re-lamping: what "type" of LED is right for you?

The ABCs of re-lamping: what "type" of LED is right for you?

In the early days of your LED re-lamp project, you’ll need to determine whether you’ll be using a Type A, B, or C replacement. The differences in each stem from whether a ballast or driver is being used and how the LED is connected to the power source. How that power gets to your lamp depends on the type of fixtures and ballasts you already have in place.

The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it

The lumen’s limits: why old measures of light output don’t always work for LEDs, and what to do about it

When replacing one light source with another, you need a medium of exchange, and lumens exist to serve as that medium. However, LEDs may be the end for the old faithful lumen. In practice we’ve found it to be a significantly inaccurate indicator of brightness where LEDs are concerned.

Should you internet-of-things your lighting?

Should you internet-of-things your lighting?

When you strip out the benefits from things that do not require networking, network lighting systems have a payback period of over 20 years and are, in our view, economically unjustified.

Quantifying quality: on measuring good light after the CRI

 Quantifying quality: on measuring good light after the CRI

LEDs are forcing an update to the CRI and a new standard is being considered that broadens the palette of test colors and adds a dimension to quality measurement. We think it's better.

On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency

On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency

Will LEDs, a technology that creates more light per unit of electricity than any commercial technology before it, increase demand for electricity? Will an efficiency technology increase overall consumption?

Buyer beware: the rise and rise of integrated LED products

Buyer beware: the rise and rise of integrated LED products

Integrated LED products are relatively new to the marketplace, appear to be the future, and may or may not be a good idea. We’ll evaluate three major lighting applications that are seeing an influx of integrated options—track lighting, downlights, and troffers—for what they cost, what the products mean for users, and where we recommend using LED lamps versus integrated LED fixtures.

The brightness you see versus the brightness you read about: on light levels, LEDs, and the shortcomings of the lumen

The brightness you see versus the brightness you read about: on light levels, LEDs, and the shortcomings of the lumen

The industry uses a measure called the "lumen" to measure light volume across light sources. Based on our installations, we believe the better quality the light, the "brighter" a lumen appears. Here we'll explore why we think the lumen fails to indicate brightness properly where LEDs are concerned and what we do about it.

From floor plan to lights on—LEDs in new construction

From floor plan to lights on—LEDs in new construction

As LED products evolve, building efficiency codes tighten, and the mental hurdle created by having to change something already in place is removed, owners and general contractors working in new construction are raring to go with LED lighting.

The LED "dark shadow" problem: a solution for retail and gallery environments

The LED "dark shadow" problem: a solution for retail and gallery environments

A challenge we often face when replacing halogen lights with LEDs is that “soft shadows” become “dark shadows”. Increased contrast between the lit and unlit sides of a rack, garment, or piece of furniture are a potentially nasty by-product of a directional LED retrofit. Here’s where the issue comes from and how we address it.

Lights out—the practical life expectancy of LEDs

Lights out—the practical life expectancy of LEDs

How long will a good LED bulb last in a commercial environment? There are so many products and variables, and many possible answers, so let’s lead with our professional opinion: 2-3 years.

Acknowledging that this is a complex and on some level impossible question to answer, here we will explain how we approach life expectancy in our LED fleet.
