Are lights on your dorm room checklist? They should be.

College dorm rooms are not known for their style and charm. They serve but one purpose for the budding student – a place to study and (occasionally) sleep. Equipped with little more than a bed and a desk, an empty dorm room requires some essential supplies. I’ve put together a list of several different types of lights — some fun and some functional — that need to make it on your back-to-school checklist.

The ever-popular rear bike light from REI that will at least make you more visible when cycling across campus at night, just not nearly as awesome as synchronized LED bike tires.

One of the main stays in Industrial and Commercial Lighting has been the Metal Halide Bulb. It is common in Indoor Fixtures, such as High Bays, Canopy Lights, Garage Lights and Low Bays. It is

So you have a Metal Halide (or even High Pressure Sodium) light, and you want to convert to LED. You’ve done your research, you’ve been inundated with marketing materials that tell you what is the most important thing to consider (coincidentally it probably is something they think is important). And now you are left to make a decision. New or retrofit? What new versus retrofit. We sell both. Our retrofits perform as well if not better than new fixtures, but not all retrofit kits can make that claim. However, if your fixtures are old, leak, and have seen their better days, then by all means replace them. It does not make sense to buy a new fixture that includes a retrofit kit inside of it like some vendors will try and sell you. The engineering of some of the new fixtures are fantastic. However, the real reason you would want to consider retrofitting is because you have a significant investment in fixtures. Why not keep that investment? Retrofitting is extremely cost effective, especially our Look for the DLC Premium Symbol, it’s different than the DLC Standard symbol. And that gives you the quick notification that the light you are looking at is the most efficient.

And why does that matter. It’s simple. It will save you a lot more money. Let me do three comparisons for you. First a retrofit kit designed at 97 lumens per watt to replace a 400W Metal Halide bulb, a second at 102 lumens per watt and ours at 155 lumens per watt. Lets keep everything else the same. Cost of electricity, hours of use. The only thing different you will notice is the watts consumed and the lumens produced. For the record, our retrofit kit uses the least amount of energy in this test BUT also produces the most amount of light. We will use 12 hours a day operating time and .12 kw.h electricity cost

Calculation 1: 97 lumens per watt retrofit head, 135 watts, 13164 lumens

Savings per fixture per year over 400 watt Metal Halide: $170.82

Calculation 2: 102 lumens per watt retrofit head, 143 watts, 14600 lumens

Savings per fixture per year over 400 watt Metal Halide: $166.62

OK, so between the competitor options, you are neck and neck, the difference is so minimal you can make your decision based on whose website you like more

Calculation 3: 155 lumens per watt retrofit head, 100 watts, 15,776 lumens (this is our LED Retrofit Kit)

Savings per fixture per year over 400 watt Metal Halide: $189.22

So there is clearly a $18.40 savings over the first LED retrofit option and a $22.60 savings per fixture over the second LED Retrofit option. And, we produce more light!

We have 3 mini LED Retrofit Kits, 30W, 45W and 60W designed to replace up to 250W Metal Halide. We have 3 standard sized retrofit kits, 75W, 100W and 120W designed to replace from 250 Watt to 400 Watt Metal Halide. We have 2 Large Retrofit Kits, 150W and 200W, designed to provide more light than a 400W Metal Halide up to 750W Metal Halide. And we have 3 Extra Large retrofit kits, 280W, 320W and 350W, designed to replace 1000W Metal Halide.

If you're like most Americans, you probably still have a quite a few incandescent lightbulbs throughout your home. Cheap, effective, and easy to use, incandescent lightbulbs provide the second most used form of lighting in the world today behind fluorescent bulbs. The history of the incandescent light bulb While Thomas Edison typically gets the credit for the invention of incandescent lightbulbs. He was far from the only person involved in their history. Technology and variations over the years include…

What are today's incandescent lightbulbs made of? Lightbulbs are comprised of a base with two metal contacts. These contacts connect to the ends of an electrical circuit and are attached to two stiff wires, which are then attached to a thin tungsten metal filament (about 6.5 feet long and one-hundredth of an inch thick formed into an inch long coil in the typical 60-watt bulb). The filament sits mid-bulb, held up by a glass mounting structure. The wires and filament are then enclosed in a glass bulb filled with an inert gas, such as argon, to reduce the loss of tungsten due to combustion. When connected to a power supply, current flows from one contact to another, through the wires and on to the filament where they heat up, creating visible light. Why they're being phased out Due to the incandescent light bulb's inefficient nature, which gives off 90 percent of energy as heat and only about 10 percent as visible light, it is giving way to the more advanced and efficient technologies cool light sources such as fluorescents and LEDs. The phase out of these bulbs by the government will help consumers:

The use of underground cables for transmission of power dates back centuries. However, the usage of these cables has remained relatively low in different regions of the world. The basic idea behind the use of underground cables is that electrical power can be transmitted in two main ways: by use of overhead electrical cables or underground ones.

Since the use of underground transmission is expected to continue growing in popularity, it is important for you to understand what underground electric transmission cables are, their nature and usage.
