We often find there is a lot of confusion between Lumens and Foot Candles and Lux. And even more confusing is how some represent conversion from traditional light sources like Metal Halide and High Pressure Sodium in terms of watts, and not lumens. So why all the confusion. Well, it may be because those who represent this conversion are trying to avoid letting you know about the efficiency of the LED lights, so they claim you can replace X watts of Metal Halide with X watts of LED. What they should really say is that you can replace a 400W Metal Halide with X lumens, and their lights only need Y watts to produce these lumens. We’ll dive into this a little later, but lets first talk about lumens vs foot candles vs lux.

What is a lumen? A lumen is a measurement of light related to (1) fixture or bulb. So when we talk about lumens, we say that a fixture or bulb creates (X) lumens. These lumens are determined by sophisticated measurement equipment.

What is a foot candle? A foot candle is a unit of measurement at a specific location in a room or outdoor location that is created by 1 to many lights. It is a cumulative reading of 1 to many light sources at a specific location. It is both real and calculated. Real in the sense that you can take a light meter and walk to any location in a room or outdoor location and take a reading that represents the amount of light recorded from all contributing lights or fixtures. Calculated in the sense that you can use software to predict the foot candles of a space based on the placement of lights within the simulation.

What is lux? Lux is identical to foot candles. It is a measurement of real or calculated light, but it is done on a different scale. As a rough estimate, 1 foot candle = 10 lux.

So, simply stated, lights produces lumens, and the cumulative lumens of all lights are then determine the foot candle or lux measurement of light at a specific point in an indoor or outdoor space.

Here in the MD/DC/VA area, it’s not uncommon for us to lose power when a summer storm rips through. And while these outages sometimes last only a few hours, storms that have occurred over the past several summers have left people in the dark for several days at a time. At Kolb Electric, we’re big fans of Generac generators—they are among the most reliable systems available, and they’re the only ones we install. That said, there are a few things you should consider if you’re thinking about installing a standby generator:

You can’t stretch the amount of power that generators supply, so make sure you receive an NEC (National Electric Code) approved load calculation with each proposal. Kolb Electric will provide this calculation with our estimate.

Standby generators must be permitted prior to installation and inspected following installation. Kolb Electric will do the work of acquiring the necessary permits for you, and we want to remind everyone not to have your system installed by a contractor who says they can do it with no permit. HOA requirements and approval processes vary, but key concerns often come down to noise and location.

In the event that your standby generator installation does not require a permit, make sure to ask if it will be installed up to NEC code.

Some people install generators to keep the essential functions of their home running, such as the refrigerator and a few lights. Others install theirs to be able to carry on with life as if nothing had happened. Before you install a standby generator, decide what you’ll want to run and what you can do without. Remember—too much capacity will needlessly inflate the cost of your system, so try to be realistic when deciding.

At Kolb Electric, we’re committed to installing your generator efficiently and effectively. Even so, the generator installation process can get hung up at different phases, such as permitting, and may take up to a few weeks to complete—especially during the busy summer months. Don’t wait until a major storm has been forecast before you install your standby generator! Try to do it during the spring or fall, before you need it (and, more importantly, before everyone else needs it!).

What type of generator will you be installing? Air cooled or liquid cooled? Is it natural gas or propane? Will you be receiving a gas meter upgrade? At Kolb Electric, we’ll talk you through your options and help make sure your standby generator does everything you need it to.

Whenever you have any sort of electrical work done, you’re not just buying the system—you’re also buying the company doing the install. With this in mind, it’s important that you know their qualifications as well as those of the technicians who will be installing your generator. Ask the following questions:

Kolb Electric has been in business since 1925, and all of our staff is licensed and trained to install Generac generators.

Standby generators require on-going annual maintenance, which Kolb Electric will provide with a service agreement. Make sure you also register your Generac generator with the manufacturer for warranty claims.

The lowest bid may sound appealing, but the deepest discounts won’t offset the costs of correcting an improper installation. When you see a huge price difference from one company to the rest, you can be sure something is being left out: load calculations, size inspections, and gas meter upgradesare just some of the areas where some unscrupulous contractors may cut corners and leave you up the creek when the big one hits.

Standby generators are designed to protect your biggest investment: your home. Take the time to get accurate answers regarding your system to keep your family safe.

Energy Efficient Lighting Solutions for Aging Eyes

As people get older there is more time to really enjoy the homes they have built for themselves. The kids have grown and moved away, and being physically comfortable has, perhaps, become more important than it once was.  Knowing that aging eyes need a better kind of light and more of it to be comfortable, remodeling the lighting in your home improves comfort threefold.

“Baby boomers are finding that they need three to four times as much light and that glare is hard on the eyes,” says Norm Brown, CLC, of Norburn Lighting & Bath Centre in Burnaby, B.C., and a consultant for the American Lighting Association (ALA). “Fluorescent light bulbs are easier to see by than regular light bulbs. LED lights are being used more for their reduced glare, as well as Halogen, for their white light quality. You can choose energy-efficient bulbs in many styles for redecorating your whole house.”

Capitol Lighting offers ceiling, wall-mounted and portable fixtures, and recessed and track lighting in energy efficient compact fluorescent bulbs as well as light-emitting diode (LED) lights to help aging eyes. Shop from thousands of fluorescent lights and energy efficient lighting solutions when remodeling your home’’s lighting at 1800lighting.com today!
