at this time the admin will give the best review with the title "Warm White LED lamps - Which are the best " ok just the following discussion:
?

For many common household lighting applications, people prefer warm white light. It is relatively easy to get just about anywhere a warm white light bulb, but if you want to save electricity and money with one of the new LED lamps, choosing a good warm white LED light is a bit more complicated. This article provides some advice and recommendations on choosing the best warm white LED lights.

When we describe as a light warm white, we refer to the color temperature. Technically, it is the concept of color temperature based on the relationship between the temperature and the radiation of a theoretical standardized material (a so-called black body) which is cooled to a state in which all molecular motion ceased. So, simply put, the color temperature is a measurement used to determine the color of light emitted by the lamp. We usually think of the color temperature in terms of whiteness or the heat of a light source: "Warm White" = 3000 Kelvin; "Neutral White" = 3500 Kelvin; "Cool White" = 4100 Kelvin and "Daylight White" = 5000 or more Kelvin.

LED lamps are available with a wide range of color temperatures, but the warm white LED lights which a light similar to producing a traditional light bulb used in general lighting in the home are more expensive because more or brighter LEDs are required in the sphere. As cool white is the natural color of the LED light, it is brighter, while chips that emit a warm white light phosphor require a "filter" to "warm" color temperature, which reduces the brightness of the chip. So, a warm white LED light is an LED lamp with a color temperature around 3000K which will produce a warm light similar to those we usually expect from a standard household light bulb.

There are a growing number of LED lamps on the market be brought to the market today as warm white lamps. Which are the best? We discuss below some of the best we have come to replace ordinary light bulbs.

C. Crane describes warm white GeoBulb as the first 60-watt direct replacement lamp that uses less than 8 watts. One of the things we love about the GeoBulb is the same size as a conventional bulb; Therefore, it is suitable for direct replacement in a covered open valve. In addition, it is one of the few lights that we have encountered, where the manufacturer-independent lumen test data have been published, so you can have some confidence that it will actually produce as much light have if the manufacturer claims - something that, unfortunately, can 't be said for a large part of the lamps there. This is a well-made product that generally has favorable ratings from customers. The GeoBulb is a good, eco-friendly alternative to standard A-line (or A-type or A-form - this is the form of a common household incandescent) bulb. As an ordinary household light bulb, it also has a standard (often called average) E26 base.

Many people today are looking for warm white PAR38 LED lamps are dimmable. As you may know, most LED bulbs will not work with a standard dimmer or those fixtures with electric eyes that automatically come out at dusk or when motion is detected. This is because LEDs require to control constant current. As a standard dimming method is used, the LED light will flash at regular intervals, or worse, simply not working. To dim a LED light, a 0-10V dimming module is needed to "trick" the LED to emit less light. In theory, all LED lamps are dimmable with this module. Thus, the lamp under one of these special dimmable LED lights, and it's a good choice for when a standard PAR38 lamp where a dimmer or perhaps replacing outside with a motion detector.

LEDinsider, which we found to have a nice range of well-made lamps and a customer sells a fully dimmable 100-watt warm white PAR38 replacement bulb with a standard base. This warm white LED generates 553 lumens and consumes only 11 watts of electricity. LEDinsider suggests that it may be used for each household 100-120 watt incandescent / halogen bulb, but by the size of the lamp, can only in places where a PAR38 lamp with a diameter of 4-3 / 4 "will correct fit. Customers have reported that they are using the balls as outdoor floodlights.

Depending on your specific lighting needs, there are a growing number of good warm white LED lamps on the market, so we recommend you take a look at the full range of LED lamps available, with great attention to product details and customer reviews.
