Philips LED A60 E27 Edison Screw Bulbs, Frosted 5.5W (40W) - Warm White (Ten Pack) (Old Pack of 1)

Product Information

To give you some idea, below is a summary table showing the most common light types and their corresponding colour temperature: The appropriate colour temperature enables you to choose the ambiance you would like for each room. Colour temperature is expressed in kelvin. The higher the colour temperature, the higher the Kelvin rating and the more blueish the colour. Light sources with a (comparatively) low temperature tend to be more reddish. CFL (compact fluorescent lamp) light bulbs were the first real energy-efficient alternative to incandescent and halogen bulbs, using much less energy and lasting for much longer. LED light bulbs take energy efficiency to another level, using around 40% less energy than CFL equivalents. CFL Light Bulb Wattage

A 100-watt incandescent bulb produces 1600 lumens of light, while a 12-14 watt LED gives off the same.Below are some tips for saving energy and lowering electricity bills. Not all of them are always possible, but implementing even a few of them can lead to savings.

Wattage is used to calculate energy consumption, and for conventional bulbs like the incandescent bulb, wattage is the primary measurement. This is because their energy consumption matters as this equals the light's brightness. The problem with these bulbs is that a lot of energy is wasted in generating light. The energy-saving light bulb, also known as the compact fluorescent lamp, is actually a folded fluorescent strip tube lamp that fits inside a regular bulb fitting.

Lumens versus watts

That being said, you can use the comparison charts below as a starting point to finding out the LED equivalents for the light source you are shopping for. LED equivalents to traditional incandescent light bulbs The term "horsepower" was developed by James Watt, who compared the output of steam engines to the power of draft horses based on how many times a horse could turn a mill wheel in an hour.

The energy consumption of an LED to an incandescent bulb is about 6:1. An LED bulb consumes about 90% less energy than an incandescent bulb. So to know the actual variation in energy consumption, you must find out the wattage of the LED bulb, some of which have been displayed in the tables above. For decades, we’ve been buying light bulbs according to wattage. But as energy-efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs. Instead of focusing on wattage, which measures power or energy use, manufacturers are indicating the brightness of their energy-efficient bulbs according to lumens, which measure light output. So while we may be accustomed to shopping for bulbs according to wattage, lumens are actually a more accurate measurement of how bright your light will be. Converting Lumens to Watts Alongside the light intensity (number of lumens), the colour temperature is another deciding factor when choosing the right LED lamp. BTU/h, BTU per hour, is a unit of power that represents the energy transfer rate of BTU per hour. BTU/h is often abbreviated to just BTU to represent the power of appliances. For example, an AC marked with a label of 12,000 BTU actually has a power requirement of 12,000 BTU per hour. The switch from incandescent light bulbs to the energy-saving compact fluorescent lamp (CFL) is something that many households are still making decisions on, and the LED vs CFL debate is one that many of us are familiar with! There are a few things to think about, and many people look to maintain the same (or higher) levels of efficiency when choosing to switch to a different type of bulb, as well as light bulb running costs. Identifying your light bulb running costs can seem confusing, so we have created a guide which outlines the running costs of each type of bulb.Did you know that the lighting in the average home uses around 16% of the total power consumption? This means the lighting in your home holds considerable cost-cutting potential! Replacing your old lamps with a modern alternative is a good start. Replace older light bulbs, particularly incandescent light bulbs, with more efficient LED light bulbs. A typical incandescent light bulb requires 75 W while an LED only requires 9 W. LEDs cost more in the short term, but if you have the opportunity to replace any incandescent light bulbs you may have, it will lead to significant future savings. CFL lights contain a small amount of mercury within the lightbulbs. No mercury is released whilst the bulb is in-tact, but care must be taken in the event of a breakage. There isn’t enough mercury within a bulb to cause harm, but it does mean that your CFL bulbs need to be disposed of correctly - your compact fluorescent bulbs shouldn’t go into a domestic bin and it is recommended that you take them to a local recycling specialist or centre for disposal. Use LED light bulbs give off very little heat in comparison to CFL bulbs which release about 80% of their energy as heat. Components The Compact Fluorescent Light is deemed one of the best because it doesn't consume as much energy as other ordinary bulbs. The fluorescent bulb however contains mercury which is a toxic liquid metal. This poses a danger when using the CFL bulb because the mercury will get released if the bulb breaks. An LED bulb uses about 40% less energy to generate light than the Compact Fluorescent Light. Below is a table showing the LED equivalent of some CFL watts.
