LED Picture light 300x300 Buying LED Light Bulbs (When Youre Used To Halogen) With LEDs, you have so many possibilities. Earlier this week, we published a post about replacing old incandescent light bulbs with LEDs. But, LED light bulbs are much more versatile than that. Their innovative construction makes them great replacements for almost any kind of light bulb.

In this post, we’ll cover how LEDs can replace halogen light bulbs.

A halogen light bulb is an incandescent light bulb filled with a halogen gas. This gas within the light bulb’s envelope helps the light last longer and use less energy to produce light. There are certainly good reasons to use halogen light bulbs, but these lights also have their shortcomings.

Before we get into how to replace halogen light bulbs with LEDs, we need to understand the pros and cons of using halogen lights:

Halogen Pros:

Color Temperature: Halogen lamps emit crisp, flattering light, only slightly cooler than a regular incandescent’s color temperature. The added blue and green tones make a halogen light bulb appear whiter and brighter than the average incandescent.
Rated Life: These lights last longer than incandescent light bulbs. A halogen light’s rated life can range from 8,000-20,000 hours, while an incandescent usually lasts around 1,000-2,000 hours.
Efficiency: They’re more efficient than regular incandescent light bulbs, generating about 10-35 lumens per watt, compared to about 8-24 lumens per watt.
Color Rendering: Halogen lights have a CRI of 100, which means they render colors perfectly. This makes them great for display lighting, accent lighting, and more.
Dimming: These lamps still generate light with a filament, so you can use them with standard dimmer switches.

LED Light Bulbs Buying LED Light Bulbs (When Youre Used To Incandescent) There’s nothing quite like the glow of an incandescent light bulb. It’s warm. It’s flattering. It’s familiar.

When you buy an incandescent light bulb, you know what to look for. You know how bright the light will be by looking at its wattage. You know what shape and size to get. You know any incandescent light will work with your dimmer switch.

Incandescent lights are easy. But if you’re still using them in every light socket, things are about to get real. As part of the Energy Independence and Security Act of 2007 (EISA), incandescent light bulbs are slowly being taken off the market. In an effort to conserve energy, consumers are encouraged to use more efficient, longer-lasting light bulbs like CFLs and LEDs.

Long story short: You might have to give up your beloved incandescent lights.

While this change might seem daunting at first, can be a great opportunity to save money on energy bills and light bulb replacements.

But what about that incandescent glow? Or those familiar features? Are they gone forever?

Thankfully, no. After years of research and testing, manufacturers have finally found a way to make LED light bulbs that mimic incandescent light bulbs to near perfection. If you’re looking to replace your filament light bulb with an LED, here’s what you need to look for:

1. For that warm, inviting glow, you need an LED with a warm color temperature. An incandescent’s color temperature is normally around 2,800 degrees K. Continue reading »

How Do LEDs Work?

bigstock LED 257x300 How Do LEDs Work? These days, LEDs are everywhere. With their impressive energy efficiency, extra long rated lives, and extraordinary versatility, they’re the lighting world’s new champion.

While it’s pretty easy to figure out what these lights can do, it’s harder to learn how they do it. If you’ve been wondering how exactly LEDs pull it off, just sit back and let this post “illuminate” you.

If you take a look at a single light emitting diode, you’ll notice that it resembles a tiny light bulb. BUT the similarities stop there. LEDs don’t have filaments like regular incandescent lights. Electrons moving across a semiconductor material cause them to create light. To understand this process, you first need to understand the LED’s components:

A diode is the simplest kind of semiconductor, which is a material that can conduct electricity. For LED lights, the conductor material is most often aluminum-gallium-arsenide (AlGaAs).

To make the semiconductor more conductive, you add atoms of another material, a process called doping. These atoms charge the conductor’s balance, either adding free electrons or providing holes for them to enter.

A semiconductor that has extraneous electrons zipping around is called N-type material for its surplus of negatively charges particles. Electrons here proceed from negatively to positively charged materials.

A semiconductor full of extra holes is called P-type material. It has, in essence, extra positively charged particles. Here, electrons can hop from one hole to the next, from a negatively charged area to a positive one.

A diode needs both N-type and P-type material bonded together, with electrodes on either end. When you connect the N-type side to the negative end of a circuit, and the P-type side to the positive end, the electrons move towards the P-type area. The holes move in the opposite direction, away from the P-type, towards the N-type.

Then, suddenly, there’s light! Continue reading »

LED Electronic Driver What You Need To Know About LED Drivers
The switch to LEDs isn’t just about trading your old light fixtures for new ones. Just like fluorescent lights need ballasts to function properly, your LED lights need something called a driver. Sometimes, in smaller LED fixtures, drivers are build right in. But, if that’s not the case for your lighting system, you’ll need to pick one out for yourself. If you’re unfamiliar with the LED driver, what it is, how it works, and the many varieties available, this post will teach you everything you need to know.

Let’s start with a basic definition:

An LED driver is an electronic device that supplies power to LED lights. To ensure the LEDs function properly, the driver converts line power to the appropriate voltage (typically between 2 and 4 volts DC for high brightness LEDs) and current (around 200-1,000 milliamps or mA). Drivers might also include dimming or color correction controls.

All this ensures that your LEDs will operate with a steady lumen output and no variation.

Before we go any further, you should note that the quality of your driver will have a significant impact on your LEDs. A good driver is about 85% efficient, reducing the efficiency of the LEDs it powers by about 15%. To make sure that your LED lighting system is the most efficient, you need to make sure you’re using the right kind of driver. Finding your perfect driver depends on such factors as the type and number of LEDs you’re using, whether you’ll place them individually or in a series, any size limitations you may have, and of course, your installation’s main design goals.

bigstock Modern stone house in Istria 9183125 1 300x144 Are LED Outdoor Lights Bright Enough?
In a word – yes.

Here’s why:

We’ve all had one of those free, or next to free LED flashlights that doesn’t give off enough light to help us see anything. So naturally, you might have some doubts about trusting LED lights to illuminate you exterior, especially at night. Unlike those cheap flashlights, LED outdoor lights – like floodlights, step lights, and landscape lights – are created for important outdoor use. So, they’ll generate enough light to brighten your stairs, driveways, porches, paths, and yards, just like any other outdoor lights.

To be sure that you’ll get lights you can trust to work and to stand out in the dark, just check how many lumens your current outdoor lights emit (halogen, fluorescent, etc) and make sure your new lights have a similar number. Continue reading »

LED Track Lighting 270x300 LED Maintenance: Give Your Lights A Long And Happy Life
When you’ve just upgraded your lights to LEDs, your first thought probably isn’t, “What am I going to do when these things burn out?” LEDs can last for as long as half a century, and when you pay for an entire LED lighting upgrade, you should expect them to. However, after you get over the dazzle and gleam of your favorite new lights, it’s important to know how their lives will play out, so you can best care for them.

This blog post will answer two questions: How do you know when to replace your LEDs? and, How should you care for them so that won’t happen for a long, long time?

1. How to replace your LEDs

The trickiest part of LED maintenance is knowing when you need to exchange your old lights for new ones. Unlike other light sources, LEDs will never burn out. Instead, they get dimmer and dimmer until they’re no longer useful, which is usually when they emit about 70% of their original light output. So the question is, how will you know when it’s time to replace your LED?

When it reaches its rated life at 35,000, 50,000, 60,000 hours, there won’t be any definite indication that it’s time to change your light bulb. Plus, depending on how and where you use your LEDs, they could last shorter or longer than the projected rated life. When they do dwindle to 70%, you might not even notice.

Here are some suggestions so you’ll never find yourself sitting in the dark with the lights on: Continue reading »

The Difference Between LEDs and CFLs: The Future

Fluorescent Lighting, LED Lighting No Responses »

May 062013

This is the concluding post in a series exploring the differences between LEDs and CFLs. To read the entire series, click here.

We’ve spent the last several weeks figuring out all the ways LEDs and CFLs are different. We’ve learned practical facts about each light source, like LEDs have longer rated lives, CFLs contain mercury, LEDs are more durable, and CFLs emit omnidirectional light (to name a few). All this makes for an excellent understanding of the current state of lighting technology.

Today, LEDs and CFLs are still rivals on the market. But will it always be like this?

The development and improvement of LED technology is still taking place, while the CFL’s technological development has reached an endpoint. It’s really thanks to LEDs that we’re in the midst of a very dynamic lighting revolution.

Since CFLs are already completely developed as a viable lighting technology, many lighting specialists think of them as the bridge between old incandescent lights and innovative LED lights. They’re an effective, efficient bridge, but a bridge nonetheless. We don’t expect CFLs to be popular forever. Continue reading »

The Difference Between LEDs and CFLs: Durability

Do you know what makes an LED different from a CFL? In this blog series, we’re explaining just that!

We all know incandescent light bulbs are delicate. You break that filament, and it’s lights out (literally). It’s easy to understand why our basic incandescent lights are so fragile – we can see and understand the simple internal structure at a glance. But, when it comes to understanding the capabilities of LEDs and CFLs, the answers aren’t as straightforward. Both light sources use more complex systems to generate light, but does this make them any less breakable?

It’s time to dive a little deeper.

LEDs:

Since LEDs don’t use a filament, they can easily withstand almost any kind of jarring vibration. When you’re rough on LEDs, transporting them from place to place while in use, or keeping them in jolt-prone spots (like in and around elevators), you don’t have to worry about easily breaking or damaging them.

The Difference Between LEDs and CFLs: Glass Envelope

Apr 302013

If you’re deciding which light source to use for your next project, look no further! In this blog series, we’re going in-depth to explore the differences between LEDs and CFLs, so you can make the best decision. In this post, we’re talking about structure…

LEDs and CFLs are built very differently.

LED light bulbs use glass or plastic envelopes of almost any thickness. They’re built to last, even in the most demanding circumstances. CFLs, on the other hand, have a daintier construction. If you drop one, the thinner glass envelope could easily break. This can be a problem, especially because CFLs contain trace amounts of mercury that will be released when the light bulb shatters.

To prevent CFLs from cracking so easily, some manufacturers have begun encasing CFLs in silicone coatings, so even if the glass breaks the shards and mercury will stay within the silicone, not allowed to get into your environment. The CFL’s traditional spiral is covered by a more conventionally shaped envelope like this: Continue reading »
