High Efficiency, Low Wattage Light Bulbs

Conserving Energy

High efficiency, low wattage light bulbs have been increasing in popularity over the past few years.  They are renowned for their economical use of energy and decreased heat emission in homes. By giving off less heat and using less energy, low wattage light bulbs can have a huge impact on the amount of electricity consumed and help mitigate the adverse effects of energy consumption on the environment. The Environmental Protection agency estimates that if American home owners were to change just one light bulb in their homes to a high efficiency alternative it would save enough energy to light 3 million more homes and prevent almost 9 billion pounds of greenhouse gas emissions per year!

Saving Money

These factors can also help homeowners save a great deal of money by decreasing their lighting and cooling costs.  Using less energy to light a home will decrease electric consumption and help cut overall utility costs.  The significant decrease in heat emission from efficient light bulbs can help relieve the costs of home cooling as well.  Investing in low wattage bulbs is the perfect way to decrease the electric bill during those hot summer months when the air conditioning seemingly never ceases to run.


Due to new government efficiency standards these alternative light bulbs will soon become the mandated standard for lighting needs.  It makes sense to begin the transition to high efficiency bulbs as soon as possible. These new lights will cost more than the traditional light bulbs of the past, but will last longer and save a great deal of money at the same time. (Plain Dealer)

There are a few downsides to these products however.  The traditional fluorescent bulbs used in in the majority of offices and homes are being discontinued after July 14th 2012 because they do not meet efficiency standards.  The new high efficiency bulbs being produced to replace them will not work in the old fixtures because of reengineered ballast that will be placed in every new light bulb.  This ballast allows the bulb to operate efficiently, but its lack of compatibility with the old fixture causes quite an inconvenience.  Light bulb manufacturers suggest having an electrician rewire the existing fixtures, or for the best results just install new fixtures all together.  Although a monetary and timely inconvenience, the switch to higher efficiency bulbs will save money in the long run.

One detriment that needs to be taken into consideration with florescent bulbs is the presence of mercury. Care must be taken when cleaning up a broken bulb or disposing of a dead one.  If the bulb is broken the toxic mercury present inside is potentially harmful if overexposure occurs.  The best advice is to clean up the bulb with plastic gloves and dispose of it properly.  Do not place it in your normal waste receptacles and do not vacuum the particles up. Because the substance is toxic, it should be disposed of separately in a plastic bag.   Some newer high efficiency bulbs are being made without mercury, but you should still consult your local lighting and waste removal representatives so you are familiar with proper disposal techniques in your area.

Quick Statistics

Here are some interesting statistics provided by the U.S. Environmental Protection Agency about light bulbs and their Energy Star rated products.

Potential Savings:  Each high efficiency light bulb can save approximately $6 a year in electricity costs and more than $40 during its lifetime.

Energy Efficiency: Low wattage light bulbs will on average use 75% less energy and last 6 times longer than the traditional incandescent bulb.

Heat Reduction: High efficiency light bulbs give off 75% less heat than incandescent bulbs and can help reduce the costs necessary to cool a home.

"I so appreciate how quickly you have responded to my numerous questions and issues. Now I know the value of a custom home builder. You truly stand by your word and your work."

Vicki H., Wildwood, MO


"Building with Mastercraft Design and Build especially with Steve and Mike was a smooth, rewarding experience from beginning to end. Working with them, the building process was very smooth throughout: from design, to build, to followup. The process as a whole can be overwhelming but they were with us every step of the way. Steve was pleasant, kind, patient and very accommodating. If he was frustrated with us, he never showed it. The quality of workmanship and materials is excellent as we feel that we received a well-built home. We are very happy with our new home."

Dan and Colleen P., Des Pres, MO


"After our home flooded due to a broken water line that ran a full night while we were not home, we hired MasterCraft Design & Build to manage the restoration.  This was a major effort as we completely lost our kitchen and most of our finished basement.  It was a significant amount of work that could have easily carried with it cost overruns and a lot of stress.  The process could not have gone better with MasterCraft.  Steve Horn and Mike Skidmore made the project truly painless, worked with us to keep their services within the budget provided by the insurance company, and kept us informed every step of the way.  I was so pleased my daughter and I then hired MasterCraft to manage the renovation of her home, with the same great results and experience."

George & Mary C., Oakville, MO


"Steve Horn of Mastercraft Design & Build is truly a professional in the field of custom home building. He uses reputable and highly qualified subcontractors who stand by their work. I wouldn’t say building a house is easy; but Steve made the process rewarding by keeping us involved in every step of the process from design to completion. Steve was easy to work with on all the upgrades and kept detailed records of the progress to stay on schedule. We have a beautiful home we can enjoy for years to come."

Len & Midge M., Mehlville, MO


"We have found Steve Horn to be not only an expert in building custom homes but also in building a custom "Green" home. We had ideas about building green that he not only put into action but helped in making sure we were doing it correctly. He has background in green design and building and used that expertise in doing our home. He is skilled in building custom homes and is a person that you can depend on. His personality is one that makes sure you are pleased with the way your home is being built and his integrity gives you the assurance that the cost of your home is what you would expect. No overcharging, no increases in building supplies, just honesty that you can depend on."

Stephen & Dawn K. - Crestwood, MO


“I have been in construction and maintenance for the past 30 years.  Over that time, I have worked with some good contractors as well as some who did not meet my expectations.  MasterCraft Design & Build is at the top of my list of outstanding contractors.  Steve helped us to create a custom design/build home and made the process very easy and enjoyable.  We love our new home and recommend MasterCraft Design & Build to anyone wanting to build their dream home.”

Mark G. - Des Peres, MO


"Last May our luck turned very bad when a 15 ton oak fell on and crushed our carport/storage room (and cars inside).  However, we had the good luck of knowing Steve Horn, the owner of Mastercraft Design & Build. Steve directed the re-build project from debris removal through the construction of the replacement structures with outstanding personal attention to details.  The quality of the work and subcontractors, as well as the attention to costs, were excellent.  We highly recommend Steve and Mastercraft."

Warren & Susan L., Ladue, MO


"We were very happy with the work that MasterCraft Design & Build did for our foyer.  Steve and his team were professional, considerate, and detail-oriented, and they always showed up on time.  When it's time to renovate our kitchen, we know who we'll be calling."
