You may have heard that LED lights cost reduction, energy saving and environmentally friendly have. All this is very true. But if you buy in the store (or online page) venture, you better know what you are doing, or you may just end up with the wrong bulb. There are five essential elements to consider:
First First, make sure you know, like what kind of bulb you replace. This seems very simple, but as a joke on computer users by the support hotline to say that your computer does not work … only to realize that they had no contact! … Select requires a replacement LED lamps that you a) the size of the base and the type of installation (ie a screw or bayonet bulb is a thin candle or globe bulbs, know, etc.).
Note the dimensions of your lamp, even within a shade or protection. While LED lighting is designed to resemble traditional bulbs, there may be differences in size.
Second Second, you must determine which is equivalent LED replacement bulbs for the elderly. It is very difficult if the products do not have the necessary information on the packaging. You are looking for one thing: the light yield. Simply put, the lumen of the measurement of light intensity. The light 10 lumens of light is negligible (just enough to find your way around a room), while 2,000 lumens of light allows you to read a book in a quarter. The reason for this is that, unlike the light bulb and a 60W or 100W, breathing the same number of lumens can be LEDs have a very different light intensities (W or W is simply a measure of the energy needed to light the lamp. In general, the more watts, the brighter the lamp).
To replace a 60W bulb, you need to find an LED 600 to 700 lumens of light offers.Well, if this is not stated on the packaging, you have no idea what you are actually buying. It may be something 5W to 12W LED on the board, so you have a wizard to have to make the light output. Most LED globes reach 50-80 lumens per watt with a few bright, even at 100 lumens per watt. Do not buy until you need less energy to light output match what you currently have.
Third Third, to look at the color of light. But from what I do not mean red, yellow, blue, etc. developed LED lighting to emit light, “white”. White light is a combination of the visible light spectrum, but do not take all the white is white. Confused? What this means is that you get LED that is similar in color light bulb – the so-called “warm white” light is slightly yellow – on the normal and daylight white and all the way up to “” cool white “, the extremely bright and is very clinical. You can see the difference look at a fluorescent light (cool white can be) and to compare the lamp in a standard (probably white hot). This is important because the nature of light, the mood changed. Use a warm, white light in an office, and you have eye strain and a dark purpose … but the use of a cold white light in your bedroom or living room and you think you are a department of the hospital!
4th The fourth thing is to look for when the light “adjustable”. While you may very well into the pattern of sunlight, not all LED lights are dimmed. This is because their electronic circuits can not operate effectively with very low power – at least they are already low power consumption. You are not dimmable damage very quickly if they are on a dimmer circuit LED – so, no. Do you prefer lights that are clearly marked to buy “adjustable”.
5th The last thing to consider is the durability and warranty. Most manufacturers rate their lamps for 50,000 hours. It’s 136 years of one hour per day … However, the guarantee of 1 year. Will you spent a lot of money, two years later, his lamp “fade” (as LED lights are not really “blow”, the only way you notice that something is not right, c, if they seemed “Sun ”). Not all lamps are the same quality, and you have to think about the manufacturer of the brand and reputation before you buy.
During this most important questions of “technical” are also remember that all lights will be profitable. LEDs are currently more expensive than conventional incandescent and compact fluorescent lamps (CFT) to buy. They were bombarded by advertising that says “low cost”, “uses a tenth of the electricity of regular light bulbs,” “Hard 50,000 hours,” etc. All this is true! But if you buy a lamp U.S. $ 20, which costs all of the above functions and use it for an hour a day (eg in your bedside lamp), which will last for 50,000 days, less than a penny one hours run .. . … but you will only break even (included with rising energy and opportunity costs) to cover additional expenditure for the purchase of incandescent lamps of 10 years.
Generally, the more you use LED lights, plus the recovery phase. Thinking about the environment and the purchase of LED lights to their carbon dioxide emissions, which will not be a problem reduces concerned, but if you try to save money in the immediate future, just the lights that are used frequently to replace.
