What is the best LED Lightbulb to replace an incandescent bulb in a living room lamp?
LED bulbs have been proven to be a superior choice than incandescent bulbs by now because of their unparalleled features. To buy LED Lamps, you can visit LV Lightings as it delivers a dimmable glow effect for a welcoming, warm atmosphere, making it ideal for general lighting applications in the hospitality industry. Its unique design radiates warm light in all directions, making it a true alternative to the incandescent lamp.
Which light bulb is the best choice for a recessed light fixture ?
There are many options to choose for recessed lighting, now with the prevalence of Light Emitting Diode (LED) technology, in addition to fluorescent, or traditional incandescent.Recessed lighting, when used in general conversation typically refers to a ‘downlight’ — a light fixture that lies flush recessed into the ceiling emitting light downwards. The fixture is often circular in shape with a specific diameter (6″ being common). Another common term is the ‘recessed can’. Other fixture types such as 2′ x 4′ recessed troffers would also fit into the category of recessed light fixture, but let’s assume you are asking about recessed cans in a residential application.Currently, LED’s as well as compact fluorescent lamps (CFL’s) are both roughly 5–6x more efficient than incandescent. (i.e. a 10W light LED/CFL light source would give the same light output as a 60W incandescent). The lamps could be integral to the fixture in the case of LED, or a pin-based system with CFL’s / or the lamps could be independent from the fixture, as in a medium base (edison base / ‘screw-in’) type, which could accommodate any of the lamp types.For a residential application as the current state of technology, I would recommend a standard medium base 4″ or 6″ diameter recessed can housing, with the use of an LED medium base lamp. The output should vary with the task, accounting for ceiling height and fixture spacing, but a common lamp to utilize in a residential application would be a 10W, 800 lumen lamp, dimmable, 2700K or 3000K color temperature. (This is equivalent in light output and color rendering to a 60W incandescent lamp). For a quality LED lamp, the cost is currently between $15 - $30, with the lamp lasting often up to 50,000 hours, around a 20+ year lifetime. This more than justifies the higher lamp cost compared to incandescent. Furthermore, the use of the medium base allows replacement with newer LED’s as the technology (efficiency, dimmability, and color rendering of the lamps continues to improve, which the industry has been doing rapidly).Hope I have shed some light on the subject!
How bright are led light bulbs?
Let me answer your question categorically. There is one difference between LED lights and the other bulbs. All the other bulbs increase slightly in intensity as the bulb is rotated to its side. Whereas with the LEDs, the intensity is not affected when you rotate the lights to either side. It goes without saying that a 14W LED lamp might be equal to a 100W halogen bulb if we look at aspects such as quality, life, etc. It is safe to say that the light that they produce is relatively coherent, it means that all the photons LEDs produce tend to travel in approximately the same direction as lasers are very coherent. On the other hand, Fluorescent/incandescent lights make photons that just fly in all directions.This means that when you look at an LED, you get most of the photons it makes flying in that one particular direction, thus there is not much less light which is flying in the other directions. LED bulbs overcome this by adding reflectors that scatter the light into a broader area. Let us look at this aspect from the point of view of temperature.Think of a lightbulb in terms of energy. You put in some electrical energy into it and pop comes out the light energy although this is not correct technically. But, at the same time you also get heat energy out of the bulb. Heat and light are inversely proportional to each other. In other words, the more heat you get, the less light you emit. That is the reason why the most efficient LED bulbs will have less heat output and won’t be as hot, too. So, LEDs are known as really bright lights because they emit all the light at one particular spot where the emphasis is laid. Instead of scattering light all over the place they tend to focus on only one spot. This is the secret behind their brightness. Hope this helps.
Is it worth it to use LED bulbs (for track lighting)?
All these people dissing LED's are obviously unaware of the newer models. I've been gradually switching ALL my CFL's to LED. The new Phillips Slimstyle LED is a great bulb and an excellent replacement for any 60 to 75 watt incandenscent application (there are smaller, 40 watt equivalents too.) Home Depot was selling them for $3.97 for a while and you can still get them most places for around $8. Besides looking nice they give a good neutral white light, not too yellow or too blue. And they stay so cool that you can touch them even when they've been on for hours. They are not visually ugly like CFL's so they would be good for some larger track light fixtures. For spot or flood type fixtures the smaller LED flood types would be a better choice. So much less heat output than any other type of lamp -- something you want to be conscious of when you're going to have multiple bulbs in an installation. And they almost never burn out so it's a good long term investment. Plus they are dimmable. What's not to love?
Do light bulbs create enough heat to make an overall difference in the room temperature?
My source is common sense, as well as being an Electronics Technician, as well as holding professional licenses for Commercial radio. Your brother is being exactly what you say he is being. He radiates more heat than 2-100 watt bulbs do. What ever heat they produce is going to come from infra-red, as well as basic radiant heat. If the room were a sealed room that was air tight, as well as super insulated, those 2 lamps, on all the time, might make a slight difference in a day or 2. Since I doubt your house is that air tight, and well insulated, any difference is psychological in nature, and not from "real" heat the bulbs generate. Besides, their heat is going to stay near the ceiling, since hot air, rises. You might want to suggest that if he stays in one place, keeps quiet, and does absolutely nothing, except breathe, he would be a lot cooler. If he wants things to be cooler, invite him to go buy LED lamps. They are available, a bit pricey, but they do exist, and would seem to be a bit cooler. Personally, his keeping quiet is the best idea. If you want a demonstration, get a thermometer, him and some of his friends to go out and exercise, then put them in a relatively small room. Check the temperature with them before they go out, and then let them see what the temperature is once they return, and gather in the room. If it is small enough, you will see a temperature rise, from their body heat. You might also tell him to stay out of your room because he only adds to the heat in it. Half a degree would not even be noticed, unless you had a really accurate thermometer. Feel free to tell him that I agree with you.
What is the most energy efficient light bulb?
In order of least to most efficient: incandescent, halogen, fluorescent, LED. Halogen is a type of incandescent lamp that lasts longer than earlier incandescents but that gives off a more intense heat. LEDs are the most efficient by far, but they are generally far more expensive -- and their light tends to be more directional, whereas other bulbs project their light 360 degrees. For this reason, CFLs are currently your best bet. High-quality CFL is give off the same light as regular incandescent bulbs and last for as much as 7-9 years. There are also easily the most economical choice for home lighting. They cost a little bit more, but they will pay for themselves in terms of energy bill savings within a matter of months -- incandescent bulbs will multiply their cost many times over during their short life because of the inefficiency with which they convert electricity into light. My recommendation would be to install CFLs now -- and to look forward to replacing them with the next generation of LEDs when the CFLs finally expire on you several years from now.
Which lighting tech is better for studying, CFL or LED?
I am not going to detail all the reasons to go to more energy efficient light technologies, but I will say, your home is filled with light bulbs (a lot more than you think!) and the choices you make concerning light technology have ripple effects in both your monthly electric bills and in your replacement time and costs. Of course, CFL's are more expensive than incandescent bulbs and LED are more expensive than CFL bulbs. But these newer bulbs are guaranteed to last longer and to use a lot less energy. In the case of LED bulbs, WAY less energy than an incandescent bulb.The light-emitting diodes (LED) are the top range lighting technology. They are extremely efficient and long lasting.Their operational lifetime is over 100,000 hours or over 11 years of continuous working. In other words, if they operate for 8 hours a day, you will not need to replace the lamp for over 20 years. Unlike the standard lights, they don't burn out and stop working unexpectedly. This ensures that you are not interrupted doing your activities. The diodes also emit lower output and hence less bright which make reading bright papers more comfortable.The energy efficiency is one of their most outstanding benefits. On the comparison to the conventional lights, the LEDs save energy by 80% to 90%. Over 80% of electric energy is converted to light energy, leaving less than 20% to be converted to heat and other unnecessary forms of energy. In overall, it cuts the electricity bill by as much as 30%. For those using solar system, it operates for much longer before draining the battery.For studying i would recommendLuminoLite RechargeableThe perfect book lightSource: Best Reading Lights
