Product Information

Note that there is no precise equivalent, and the more significant part is an approximation. Another disparity comes with the various available products so that the equivalent will vary slightly from one product to another. British thermal units (BTU) are a measurement of heat used as part of the Imperial and US customary units of measurement. It is defined as the amount of heat that is required to increase the temperature of 1 pound of water by 1 degree Fahrenheit. Heat is a type of energy, so BTU can be directly compared to other measurements of energy such as joules (SI unit of energy), calories (metric unit), and kilowatt-hours (kWh). 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.

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. Let's imagine that you are looking for an extremely bright bulb that emits 1,300 lumens. For an LED bulb, producing 1,300 lumens will require around 15 watts of power. However, for a less-efficient halogen bulb, over 60 watts of power When replacing an incandescent bulb or a halogen lamp, you will now have to choose between a LED or a compact fluorescent light. But what exactly is the difference? Use the calculator below to estimate electricity usage and cost based on the power requirements and usage of appliances. The amount of time and power that each appliance is used varies significantly between households, so for the best results, adjust the usage for each appliance to most accurately reflect your personal usage. Typical appliance:To explain this better, when your bulb is a 60-watt LED equivalent, it implies that the LED bulb's brightness is equal to that of a 60-watt incandescent bulb. This has nothing to do with the LED wattage but rather its lumen. As a result, you can use an LED bulb of a greater equivalent, such as a 100-watt equivalent, as long as it doesn't exceed the 60-watt energy consumption limit. LED and CFL bulbs can be useful to serve different purposes, depending on the type of light that is needed for an environment. LED Lights can emit light in a specific direction, ideal for use as downlights in kitchens, bathrooms, hallways or for task-based lighting (e.g. reading). However there are also directional and wide beam angle LED lights available, providing more control of light angle and spread. In comparison, CFL lights provide widespread light, and so tend to be used in offices, schools or shops, but would not be suited for more specific lighting tasks such as downlights or reading lights. Efficiency 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. most CFLs take a while to work up to full light intensity, which makes them unsuited for use in places where the light is switched on and off for short lengths of time (like the toilet). Incandescent light bulbs are the least energy-efficient light source, with LED light bulbs using just 10% of the energy to produce the same amount of light as their incandescent equivalents. Incandescent Light Bulb Wattage

LED lamps are made up of clusters of light-emitting diodes (LEDs). As they are so small, LED lamps come in all shapes and designs. 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 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.

Horsepower (hp) is a unit of power most commonly used to reference the output of engines or motors. There are a number of different definitions of horsepower. Two of them are mechanical horsepower and metric horsepower.
