GUIDE-Upgrade-To-LED-1023-V1 Upgrading to LED Traditionally, Lamps (Light Bulbs) were designated by their wattage which implied the brightness and luminous efficiency of the lamp. Today however, the more efficient LED Lamps can achieve the same brightness, measured in lumens, with much less power. A typical data table for a new LED fitting will include the below example options: NO. LED LAMP SPECIFICATIONS: 01 Luminaire lumens (with diffuser) 2950 lm 02 Lumens from chip (no diffuser) 3295 lm 03 Useful lumens 2850 lm 04 Rated Wattage 23W 05 Nominal life time of the lamp 50,000 hrs 06 Colour temperature 4000K 07 This product contains a Light Source of Energy Efficiency Class D 08 Flicker free operation THE ENERGY TABLE EXAMPLES EXPLAINED: 01) Output lumen measurement based on entire fitting as it will be fitted (with diffuser) - this is the measurement that you will use to determine what is right for your light output levels. This is also the lumen data used when calculating lm/W (Lumen efficacy). 02) Output lumen measurement based on just the LED array output (without diffuser). 03) Useful lumens is a unit of measurement of the visible light output within a 120 degree beam angle. 04) Rated Wattage is the amount of power needed to achieve the stated lumens outputs. 05) Amount of hours on average the fitting will last for. 06) A low temperature (3000K) will have a warm orange glow and a high temperature (6000K) will have a clean blue glow - see our CCT guide for more info on this. 07) From 2022 Energy Efficiency has been re-scaled. What was an A rated LED fitting in 2021 could now be a `D' or `E ` Class but this is only relevant to the actual LED not the fitting itself. Energy tables are calculated based on the output of the light source (LED/Array) divided by the power consumption and multiplied by a correction factor which depends on whether the light source is Mains or Non-Mains powered and whether the light source has a directional or non-directional beam angle (Directional =<90 degrees). 08) An LED driver converts the current from AC to DC and steps down the voltage so you get a constant current to your LED's - eliminating any visible flicker. CFL / Fluorescent / Halogen Lamps É LED Lamps É LED Array SAVE MONEY, REDUCE YOUR CARBON FOOTPRINT AND GET BETTER PERFORMING LIGHT FITTINGS 4 Reduce Lighting Bills by up to 80%: LEDs use up to 90% less power than traditional incandescent light sources and offer the potential for a noticeable and significant reduction in energy costs and power consumption 4 Mercury Free: unlike fluorescent lighting, LEDs are free from this RoHS restricted substance 4 Instant Light: unlike fluorescent lighting there is no `warm up' period LEDs provide instant full brightness 4 Operating Temperature: LEDs can perform well at low temperatures, increasing the areas within which these can be installed LUMENS TO WATTAGE CONVERSION CHART Lumen Brightness Lamp Type 220+ 400+ Lumens Lumens 700+ Lumens 900+ 1300+ Lumens Lumens 1700+ Lumens 1900+ 2100+ Lumens Lumens 2500+ Lumens LED 3W 5W 8W 10W 15W 19W 21W 23W 28W CFL 5W 7W 12W 13W 21W 26W 28W 32W 34W Halogen 20W 35W 40W 50W 75W 90W 95W 100W 150W USEFUL NOTE: It is also advisable to look at the lamps "average lifetime" (no. 05 in the lamps specification table example). An LED lamps average lifetime is usually much much longer which means you don't need to keep buying them regularly to replace them (unlike traditional fittings).Adobe PDF Library 17.0 Adobe InDesign 18.4 (Windows)
