Purchase Light Bulbs That Serve Your Needs
Apart from lower power consumption cold cathode bulbs last much longer than incandescent bulbs which compensates for their initial cost. They do not emit much heat like their predecessors hence their name. Other more efficient bulbs used indoors are the halogen bulbs which are used for spot lighting applications like reading or illuminating a room's centerpieces. They require a halogen transformer because they are adapted from car headlight technology which uses a different power source. They produce a lovely light but they require special covers because they emit heat at very high temperatures. The halogen transformer converts the normal ac current in a room to direct current of 12 volts or 24 volts. A home should therefore have several halogens lamps for every halogen transformer for cost effectiveness. More recently, halogen lighting has been used with power sourced from solar panels thus eliminating the need for halogen transformers altogether.
When looking to purchase light bulbs for outdoor purposes, the best choice is the hps light bulb. It stands for high pressure sodium light bulb which is commonly used for premises security lighting. The hps light bulb produces very bright light and does not distort the color of the objects it illuminates. For a longer range of lighting, metal halide floodlights have been in use in many arenas and theaters. Metal halide floodlights are now gradually being replaced by LED lighting systems that consume less power, take up less space and produce less heat.
LED bulbs can be used for both indoor and outdoor lighting, they are dimmable to any extent without damage and can be easily programmed to change light or to only light at certain instances. LED bulbs do not however produce a bright enough light as hps light bulbs for outdoor purposes or cold cathode bulbs for use indoors. Those are the facts to consider when you want to purchase light bulbs.
