Bathroom Lighting Tips

!±8± Bathroom Lighting Tips

So, you've been putting up with the tacky light fixtures that were installed when you moved in. Or worse yet, maybe you still have the bulb and string hanging from your bathroom ceiling. But more and more people often, the bathroom is used as a sanctuary, a place to relax after a long day. Steam showers, Jacuzzis, and more spacious rooms are partly the reason. Whats ofter overlooked is the lighting, which can make all the difference when it comes to aesthetics and utility. The secret to good bathroom lighting is layering the light. Layering, refers to using different sources of light. In the bathroom, it involves using both general lighting and task lighting.

The first Layer

The fist layer, as mentioned, starts with ambient or general lighting. The goal is to provide a warm glow to the room by providing a comfortable level of brightness without any glare. The most common sources of general light for the bathroom is a flush or semi-flush ceiling fixture. It is also becoming more common to use a mini-chandeliers in the bathroom. Ambient lights need to be placed in the center of the bathroom so that the light is spread out evenly.

How much general light do I need for my bathroom?

The rule of thumb for the first layer of lighting in the bathroom is as follows. Multiply the length and width of the bathroom- lets say 10ft. by 10ft. Take that number and multiply it by a factor of 1.5. So in the example above, you would need 150 Watts of general light as your fist layer.

The Second Layer

The second layer is task lighting. Portable lamps, tracks, and recessed lights are usually the sources of task lighting. However, these sources don't work well at all in the bathroom. If you have a recessed light above the vanity mirror you've probably notices the shadow it casts on your face. It is not suitable at all.

Placement of bathroom sconces and bath-bars

Proper task lighting in your bathroom should surround you with light. The ideal source of task lighting would be two sconces on either side of the vanity and a bath-bar above the mirror. Sconces should be place about 6-8 inches above eye level or about 6 1/2 feet from the ground. They should also be separated by a distance of 28 inches or more. The bath-bar should be 30-32 inches in length, mounted above the mirror. FYI, many companies now offer "beauty wraps." These fixtures wrap around your mirror, providing you with sufficient light.

How do I determine the amount of task lighting in my bathroom?

Calculating the amount of task lighting is similar to the example given above. The only difference is you multiple by a factor of 2.5. In the example given above, that would amount to 250 Watts of light.

Energy-Saving Light Bulbs - Why LED Lighting Is Taking Over From CFL Light Bulbs

!±8± Energy-Saving Light Bulbs - Why LED Lighting Is Taking Over From CFL Light Bulbs

If you have been working on making your home energy-efficient, you have probably replaced most of your old incandescent light bulbs with energy-saving light bulbs. Until recently this was considered a big step forward. Those curly CFL (Compact fluorescent) bulbs sprout from lampshades all over the home and we think we are doing our bit for the environment. But now that LED lighting has become so much more versatile, it is replacing the CFL bulbs and showing them up as not quite as green as we had thought.

The danger of the CFL energy-saving light bulbs has been much talked of recently. They contain mercury which is very poisonous. Because they are fragile, breakages happen easily. A lamp just has to be toppled over, knocked by a cat or a child, and the bulb breaks, exposing the family to this toxic substance, as well as to shards of broken glass. Disposing of the used light bulbs is also problematic and if they are not properly recycled can be extremely harmful to the environment.

Although CFL bulbs are considerably more energy-efficient than the old incandescent bulbs, LED bulbs out-class them both in energy-efficiency and life-span. LED lights are 30-50% more efficient than CFLs and their lifespan is five times longer - that is 50,000 hours as opposed to less than 10,000 hours of the CFLs (and, let's face it, many CFLs have met with an accident long before they have achieved their optimum lifespan).

CFLs, despite being promoted as a green alternative to incandescent bulbs, are not actually that good for you. They emit harmful UV radiation and can add to electromagnetic pollution within the home, causing sensitive people a variety of health problems.

So why haven't LED s already taken over from them completely? The problem, as always, is cost. LEDs still cost more than CFLs to purchase initially. In the long-term, however, you save considerably, both in your reduced electricity bills and in the amount saved on replacing used bulbs. Because LEDs are solid and have no fragile components, they are very durable, so your investment in one LED light bulb could last you for more than ten years. The bulb will have more than paid for itself in two years, so after that for the next eight years you are saving money all the way. Finally there is a green energy-efficient lighting solution for eco-friendly homes.
