Time to start replacing bulbs?
So, I want to take a minute and talk about lighting. I almost said “light bulbs” but realized that tends to imply traditional lighting. The fact is lighting is getting to be as high tech as anything in the market. It’s almost more than a standard consumer could handle. This morning I noticed that a light in my bathroom had “burned out.” I also noticed it was a 75W bulb. I spend most of my day thinking about numbers in the mW range and getting up to 4-5W, so the idea of 75W for a bulb really hit home. Obviously, it wasn’t the first time I’ve thought about how inefficient light bulbs are, but it did occur to me that this would be good fodder for this blog. I also decided it was time to kick-it-up-a-notch at the Risser house and start upgrading our house to become more energy efficient. Walk the walk.
But what are my options. Time to research and learn. The internet being what it is, it took all of 5 minutes to find some basic descriptions of the options and a cool video to educate myself on all things lighting.
Basic Lighting Options:
Incandescent bulbs have been around since 1810, using a filament that’s heated to the point where it glows. The glowing filament produces the bulb’s light and a good amount of heat.
Halogen bulbs operate on the same principle as incandescent bulbs. The evaporated tungsten mostly deposits onto the inner surface of the bulb. The halogen sets up a reversible chemical reaction cycle with the tungsten evaporated from the filament. The halogen cycle keeps the bulb clean, and the light output remains almost constant throughout life of the bulb. The halogen bulb operates at significantly hotter temperatures than the incandescent bulbs.
Compact fluorescent bulbs (CFL) have an electric current and a high voltage flow between electrodes at each end of a tube containing gases. The reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb. The bulbs contain 3-5mg of mercury per bulb.
Light Emitting Diode (LED) bulbs use a small electrical current passing through a semiconductor material to illuminate the tiny light sources called LEDs. The heat produced is absorbed into a heat sink, keeping the bulbs cool to the touch.
So, what am I going to do? Probably, I will try some options and see if my boss (Mrs. Risser) screams about the way the “light looks” She is VERY particular about the color of light, and also how fast it comes online. Stay tuned and I’ll let you know how it all turns out.
