My first impression when I opened the package to get a look at a GeoBulb was this thing is heavy. I would speculate the GeoBulb weighs three times as much as a regular Thomas Edison style light bulb. Also, it is much heavier than a CFL with the same light out put.
It is well made using a thicker glass globe than a standard light bulb. It is shaped and looks very much like a standard light bulb except for the cooling fins.
The cooling fins artistically reach upward from the base, like flower pedals holding the glass globe. The fins are made of white perforated metal, likely aluminum, to give a large surface area for air-cooling.
Unlike the EVOLUX LED bulb, there is no cooling fan in this bulb. No fan and no noise.
The fins do get warm. Not skin scorching hot but too warm to hang onto for long. When I scanned the GeoBulb with my infrared thermometer, I got readings between 130 and 148 F. Nowhere near as hot as an incandescent bulb.
When I get a new product, I read all the sales literature that is provided because it helps me set up standards to check the product against. The claims made for the GeoBulb are not exaggerated.
The box says it is intended to replace a 60-Watt incandescent using only 7.5 Watts. It puts out plenty of light to do the job. My Kill-A-Watt meter says it uses 7.0 Watts.
The color quality of the light from the GeoBulb is a little more bluish white than the light from the standard light bulb. The bulb I received is labeled “Cool White” indicating that the cool blue light is by design. The GeoBulb is available in Soft White or Warm White. They tend more toward neutral or yellow light. Some folks don’t like the blue white light so I would suggest trying a Soft White bulb first for more natural color appearance.
Like other LED bulbs, this one sends more light straight up from the bulb than it sends out side ways. However, the GeoBulb sent almost twice as much light out to the side as the more powerful EVOLUX bulb that I reviewed before.
Does the GeoBulb save money?
Yes, if you are comparing it to an old fashion incandescent 60-Watt light bulb.
No, if you are comparing it to a 13-Watt Compact Fluorescent Lamp (CFL).
I checked the math on the press kit information and it all checks out, so I’ll use their data. Over a 30,000-hour usage time, the total cost for energy plus the purchase of the bulbs. The numbers look like this.
60 Watt incandescent $231.96
13 Watt CFL $104.73
7.5 Watt GeoBulb $145.76
From a home money saving point of view, the clear winner is the CFL.
For commercial and industrial applications it is easy to justify the investment in high cost LED lamps with the maintenance labor cost savings alone. The very long service life of LED bulbs makes changing them very infrequent. Any time a company is paying someone to change light bulbs, the cost of labor becomes the dominate cost factor, not the price of the bulb.
Using the data provided by C. Crane Company I graphed out the total cost for each type of bulb over the 30,000-hour life of one GeoBulb to help visualize what happens.
In order to match the cost effectiveness of the CFL the GeoBulb would have to get its selling price below $80 each. Less than that, if it were to save folks money at home. Currently the GeoBulb costs about $120 each
Who would pay so much for a bulb that looses them money?
I believe that there are two basic reasons for folks to buy and use the GeoBulb.
First, there are people who are willing to pay more for products that have a very low environmental impact. The GeoBulb has a very low carbon footprint because of its low power consumption. It is a green product because it does not contain lead or mercury. The green GeoBulb is well suited for reading lamps that point down toward the work area.
The second group is folks who live “off the grid.” They generate their own electrical power instead of buying it from a utility company. Folks living off the grid usually have a very limited amount of electric power that they make themselves using solar cells, wind turbines, water wheels or a combination of these. The GeoBulb with its very low power draw is just what these folks need to help them stay off the grid.
The GeoBulb is the best LED lamp for home use that I have seen so far.
The GeoBulb is a product of the C. Crane Company and comes in an easy to open box that does a great job protecting this valuable bulb. They are to be commended for very truthful labeling and advertising of a good product.
Will I buy them for my Home?
No. I use bulbs that are 100-Watt or 150-Watt “size” because our old eyes need the more intense light. We use a mixture of CFL’s and special color incandescent. CFLs to save money and the special color incandescent bulbs to keep my wife’s color sensitive quilter’s eyes happy.
I am hopeful that the technology will continue to develop so that brighter LED bulbs become available for home use that will save money for folks who pay the utility bills.
