90000 LED Lighting Calculator | LED Cost Calculator 90001 90002 Take advantage of our LED (Light Emitting Diode) Lighting calculator and determine just how much you can save annually on your power bill, when you upgrade your home or office’s lights to LEDs bulbs. LED light bulbs consume less energy than incandescent and compact florescent light (CFL) bulbs, and last much longer and they make much more efficient use of the power supplied to them. 90003 90002 LED light bulbs require just a fraction of the wattage required to power a traditional incandescent bulb.For example, 60 watt incandescent bulb will net you the same amount of lumens, units of light, as a 7 watt LED bulb — and the LED bulb would last roughly 40 times longer than the incandescent. 90003 90002 The epoxy build of LED light bulb makes them much more durable than glass and copper builds of traditional light bulbs, potentially saving you money on replacing broken bulbs. The light emitting diode features a positive and negative lead, which only allows power to pass through in one direction.The unidirectional power flow helps to eliminate shorts, and ensures that LED bulbs have long lives. 90003 90002 The diode itself is also extremely proficient in utilizing the every bit of power that’s feed into it, while traditional bulb may lose up to 80 percent of input power due to heat dissipation. Try our FREE calculator, and then customize the widget for your website! 90003 90002 Our LED Lighting Calculator factors the following variables to determine your energy savings: 90003 90012 90013 Number of Bulbs 90014 90013 LED Wattage 90014 90013 Current Bulb Wattage 90014 90013 Hours of Use 90014 90021 90002 After you’ve completed the fields in the LED Lighting Calculator, simply click on the «Calculate» button to view your annual electricity savings.You’ll also to calculate the amount of carbon emissions you’ll be cutting by making upgrading your home or office’s lights to LED bulbs. 90003 90024 Tips and Considerations 90025 90002 The annual saving are based at rate of 20 cents per kilowatt hour. 90003 90002 The «Hours of Use» section of the LED Lighting Calculator concerns your daily averages for light bulb uses. To determine how many hours you should enter into the field, take an estimate for each bulb’s daily usage. Add each bulb’s estimated hourly usage, and then divide the hourly total by the total number of bulbs to find out your home or office’s daily light bulb usage.90003 90002 It’s likely that all of your home or office’s bulb are not of the same wattage. Like your «Hours of Use» estimate, you’ll also need to determine an average bulb wattage to complete the LED Lighting Calculator’s «Current Bulb Wattage» field. Add the total amount of watts of your current light bulbs, and then average that number by the total number of bulb. 90003 90002 Get even more precise and average the total wattage of your prospective LED bulb, using the same formula you used for the «Hours of Use» and «Current Bulb Wattage» fields.90003 90002 You may also be interested in the LED Resistor Calculator as well. 90003 90002 Let’s be honest — sometimes the best led lighting calculator is the one that is easy to use and does not require us to even know what the led lighting formula is in the first place! But if you want to know the exact formula for calculating led lighting then please check out the «Formula» box above. 90003 90002 You can get a free online led lighting calculator for your website and you do not even have to download the led lighting calculator — you can just copy and paste! The led lighting calculator exactly as you see it above is 100% free for you to use.If you want to customize the colors, size, and more to better fit your site, then pricing starts at just $ 29.99 for a one time purchase.

Design Calculation in a Building — Electrical Wiring Installation 90004 90005 90006 In professional field proper 90003 lighting design 90004 is very important because an under lighting arrangement will decrease the efficiency of the task for which the lightings were designed and an over lighting arrangement will result in over expenditure of the company. On small scale this difference is not too much to worry about but in large buildings, plants, factories, etc it becomes very significant in today electrical wiring installations.90009 90006 The simple and basic approach for 90003 calculating the lighting 90004 requirement is to divide the total light requirement of the room by light output (lumen) provided by a single lamp. Although this is the basic approach for an average household room, but it’s not practically accurate. 90009 90006 In practical there are several other parameters which are necessary to be considered in the calculation because nothings Ideal. For example the luminaries lumen output will not be the same throughout the entire life span, dust deposition on lamps will also reduce their output over time which means cleanliness is also an important parameter.A bright painted room reflects more light than a dark coloured room so they both have different lighting requirements. 90015 90015 90009 90006 So it is important to first understand few 90003 90020 basic terms about lighting design 90021 90004 before beginning the calculations. 90009 90006 90003 90026 Room Index- 90027 90004 It is based on shape and size of the room. It describes the ratios of the room’s length, width and height. It’s usually between 0.75 to 5. 90009 90006 90031 90031 90009 90006 Where «90003 90020 l 90021» 90004 is the length of the room, 90009 90006 90003 90020 «w» 90021 90004 is the width of the room and, 90009 90006 90003 90020 h 90049 wc 90050 90021 90004 is height between work plane i.e. Bench to Ceiling 90009 90006 This formula for Room Index is applicable only when room length is less than 4 times the width. 90009 90056 90003 90026 Maintenance Factor 90027 90004: 90061 90006 It is ratio of the lamp lumen output after a particular interval of time as compared to when it was new. The lumen output of a light fitting decreases with time because of aging of many of its components by internal (saturation of elements) or external factors (dust deposition). For example maintenance factor of a light fitting used in a cool dust free area will be better than the light fitting used in hot and dusty area.90009 90006 90065 90065 90009 90006 It is less than or equal to 1. 90009 90006 Typical values used for the lighting calculation are: 90009 90072 90073 0.8 — For offices / classroom 90074 90073 0.7 — For clean Industry 90074 90073 0.6 — For dirty Industr 90074 90079 90006 Read More: Light Emitting Elements And Their Types 90009 90056 90003 90026 Room Reflections 90085 90027 90004 90061 90006 The room is considered to consist of three main surfaces: 90009 90091 90073 The ceiling 90074 90073 The walls 90074 90073 The floor 90074 90098 90006 The effective reflectance’s of these 3 surfaces affect the quantity of reflected light received by the working plane.Light colors like white, yellow will have more reflectance compared to dark colors like blue, brown. 90009 90056 90003 90026 Utilization Factor 90027 90004 90061 90006 Utilization factor (UF) is the ratio of effective luminous flux to the total luminous flux of light sources. It is the measure of the effectiveness of the lighting scheme. 90009 90006 It depends upon 90009 90072 90073 The efficiency of luminaire 90074 90073 The luminaire distribution 90074 90073 The geometry of the space 90074 90073 Room reflectance’s 90074 90073 Polar curve 90074 90079 90006 Read more: What is Energy Efficient Lighting and Techniques to Implement It 90009 90056 90003 90026 Space to Height ratio 90027 90004 90061 90006 It is the ratio of distance between adjacent luminaires (centre to centre) to their height above the working plane.90009 90006 90134 90134 90009 90006 Where, 90009 90072 90073 H 90049 m 90050 = Mounting height 90074 90073 A = Total floor area 90074 90073 N = No. of Luminaires 90074 90079 90006 It should not exceed maximum SHR of the luminaire as provided by the manufacturer. 90009 90006 90003 90026 Note: 90027 90004 A normal living room requires 20 lm / ft 90156 2 90157 i.e. 215 lm / m 90156 2 90157 90009 90006 For Studying room i.e. Classroom 300 lm / m 90156 2 90157 is required. 90009 90006 (Note that for different environment and conditions there are different standards.For example companies like many MNC’s should maintain 600 lm / m 90156 2 90157 in the Office’s for people working in night shifts) 90009 90006 Now let’s start with the steps. Consider the following layout of a particular floor of the School and analyse the lighting requirements of different sections of the floor. 90009 90006 For ease of the calculation all the light fittings and their ratings taken into account are of Phillips make.
