Last week we introduced the topic of Total Cost of Ownership (TCO) for lighting. In the post we showed a simple equation to calculate the TCO of a bulb. The cheaper or less expensive upfront cost of a bulb may not always be the best option in the long run. Factors including the wattage, kWh rate, product cost, rated life, are all considered in your cost of ownership.
There are other ways to save when considering a switch to energy efficiency lighting such as LED. In addition to your long-term cost savings, utility sponsored rebates are an excellent way to reduce your upfront or initial costs- further reducing your Total Cost of Ownership.

When deciding which light bulb to purchase, the cost of the bulb can be a major factor in your decision. But the cheapest bulb on the shelf might not always be the least expensive option in the long run. The truth is that the bulb you buy will determine your cost in the long term. Some bulbs cost more to use, operate, and maintain than others. These costs, all together, are known as your total cost of ownership. Total cost of ownership (TCO) is a financial estimate intended to help consumers and business owners determine the direct and indirect costs of a product. In terms of lighting, the cost of ownership takes into account the upfront cost of the product, the hours used, kWh rate, and the rated life of the light bulb.

Everyone wants to be energy efficient these days: it can help to reduce energy costs- key for all businesses.
If you’re happy with the performance, light output, layout, and appearance of your current lighting system then there’s no need for a full replacement of your fixtures. Retrofit kits let you improve upon the existing fixtures without having to go through the time and cost of replacing them. Not only are they fast and easy to install, but they are one of the most cost effective way to save on lighting. Depending on circumstances, they may even qualify for available utility rebate programs.

With July 4th behind us, it’s officially summer and time to think about your outdoor lighting needs. Here are some of our favorite products to light the night!
Anytime you’re outside in the summer, there’s one thing that’s sure to ruin it: bugs. The problem tends to be worse at night because traditional lights attract them.
Most people are so used to seeing bugs on their outdoor lights they’ve never wondered why, or how to stop them. Insects see light differently than people do, and they’re most attracted to shorter wavelengths—light at the far end of the spectrum, close to ultraviolet light. So all too often, the most attractive light in the area will be the manmade outdoor light around your deck, porch or patio.
Bug lights use filtered yellow glass to minimize the short spectrum light—so they don’t attract insects. If you haven’t yet, this summer is the time to switch.

Most of the time it’s easy to see when technology is improving: new smartphones roll off the shelves every few months. But for other technologies, change can be harder to recognize—especially if you’re used to your current set up.
According to the Department of Energy’s (DOE) Commercial Buildings Energy Consumption Survey, which is the most current data available, more than 2 million facilities built between 1980 and 2003 have been using the same lighting systems for the past few decades- despite the number of advances in lighting technology made since then. Three quarters of commercial buildings have outdated technology.
Do you know if yours does?

277 Volts is the input power of choice for most industrial and commercial applications. High voltage lighting is better from an efficiency standpoint. Higher voltage means less current, which means less power loss from resistance as stated in Ohm’s and Joule’s laws.
Ohm’s law: Voltage = Current*Resistance
Joule’s law: Power = Voltage*Current
High voltage lighting means you can put more lighting fixtures on a given circuit because voltage drop is less of a concern. This means these lights are ideal for areas with a lot of lighting fixtures close together: think warehouses, offices, restaurants, hotels, schools, and even hospitals.
Most industrial facilities get their power in a 480/277 volt 3 phase 4 wire system, because 277 is the phase-to-neutral voltage for 480’s phase-to-phase. The 480 volt wiring is generally used to power large industrial equipment, and the 277 volt wiring powers industrial scale lighting. These two voltages tend to go together because you do not need a transformer to use the 277 voltage, which cuts down on energy and construction costs.

This Earth Day, Bulbs.com is counting down our favorite ways to go green, with some practical tips and considerations to keep in mind during the celebration of our planet and throughout the year.

To give back to the entire planet, we offer a single hour — a day at most? What is this Earth Hour, and why does it matter?
Earth Hour is an international movement started by the World Wildlife Fund, encouraging you to switch off non-essential lights for one hour, and perhaps more critically, to inspire a trend toward engagement with energy efficiency and environmental awareness.
This year, Bulbs.com will be participating in Earth Hour, a World Wildlife Fund sponsored world-wide event happening this Saturday March 28th from 8:30-9:30 PM.During Earth Hour, we will be turning off non-essential building lighting and encouraging our employees to do the same in support of a broad range of environmental issues. Additionally, Bulbs.com supports the transition to energy efficient LED lighting and its positive environmental impacts.
