LED tube lights use between 40 and 50% less energy than fluorescent tube lights, which is of course comparable to CFLs that utilise the same technology. Fluorescent Tube Light Wattage How many lumens are in a watt? Because lumens measure brightness and watts measure energy output, there is no simple method for converting wattage to lumens. With energy-efficient lighting like LEDs and CFLs, how many lumens are in a 60W bulb or 100W bulb depends on the lumen output of the bulb, not its energy use. 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.

lm per watt is the amount of light produced by the new type of lights. We can see that a 3 watt spotlight would produce 300 lm, not 600 lm, so it’s definitely not the same as a 50 watt bulb. How bright is a 4w LED bulb? G9 led bulb has a 5 watt equivalent to 28 watt 33 watt 40 watt halogen bulbs. WHAT LED is equivalent to a 1000W halogen? Chip on Board (COB) is the most recent development in LED technology using chips with multiple diodes (typically 9, or more). There is no casing with COB technology which enables a much denser LED array of light compared to SMD. A consistent and controlled light beam is given off, without any visible individual light points, thus offering great optics. COB offers a greatly improved lumen per watt ratio compared with other LED technologies such as DIP and SMD. COB technology gives the best conditions for optimal cooling, which in turn will increase efficiency and lengthen the overall life of the lamp. What colours are LED bulbs available in? When it comes to getting the lumen equivalent to a watt, it’s useful to consider that we’re now measuring light bulbs by light output, rather than energy use. LED equivalent wattage measurements are also based on elements such as the colour temperature and quality of the light bulbs themselves, so it makes sense to compare lumens of the same type of light bulb for a more accurate measurement. LEDs (light-emitting diodes) are a type of electronic light source. LEDs are different from conventional light sources such as incandescent and halogen lamps. They last much longer, consume far less energy and emit very little heat. They are highly durable and do not feature fragile elements such as glass tubes or filaments; they are also safer because they do not contain any mercury or lead. LED bulbs are now available in the most common light fittings, including GU10, B22, E27 and MR16. How much power do LEDs use?The goal is to give a room a brighter light. If you have a small room and a bedroom, then this isn’t ideal. When you’re about to go to bed, you don’t want to blind yourself. If you want to light a 200 square foot living room, you should use 2,000 lm. What is 13W LED equivalent to? LED equivalents to metal halide lighting offer similar energy savings as over sodium lighting – around 50%. Metal Halide Light Bulb Wattage 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. Lumen gauges the quantity of visible light, which is the light's brightness level. This is because such bulbs do not require ample energy to generate light; instead, they use lesser power but shine brighter. Nowadays, it's no longer the watt used to measure brightness but the lumen, while the watt is used to measure energy utilization. You may be more familiar with light bulbs being measured by their wattage, with watts being the primary unit of measurement for standard light bulbs. However, many manufacturers are now stepping away from wattage, which measures the power of a light bulb, and instead label their bulbs by lumens. Lumens are an accurate measurement of brightness, and all energy efficient light bulbs, such as LED light bulbs, are now labelled by lumens accordingly.

Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use. Thankfully, LED bulbs exist as replacements for most caps, shapes and sizes so there’s always an LED for you. Around 40% less energy is used by the light bulbs that are powered by the LEDs. How much does it cost to run a 60 watt LED light bulb for 24 hours? The pace at which LED technology is growing is truly incredible, although they’ve now been around for many years, today’s LED technology has completely changed lighting as we know it. We’ll be the first to admit that the process hasn’t always been consumer friendly, and we’ve compiled this guide to help you understand how any why you can benefit from making the switch. What is an LED? 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

Cost of electricity will vary. The figures used above are for comparison only, and are not exact. Residential energy costs among the various states range from 35.17 cents (Hawaii) to 11.4 cents (Washington) per KWh. 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. give you a more accurate indication of how much light to expect from an LED. Metal Halide / High Pressure Sodium to LED Wattages Conversion

SMDs (Surface Mounted Device) are the new generation of LED lighting, the majority of our bulbs contain SMD chips allowing our bulbs to be much brighter than older generations of LED. The LED is soldered directly onto the PCB therefore requiring less space and improves the thermal connection. What is a COB LED?With today’s efficiency, you can replace 1000W Metal Halide with as little as 120W LEDs. Is 3000 lumens bright enough?
