Rated Current (\(I_{N}\)): The Maximum Current That The Device Can Carry Indefinitely. The Most Popular Ratings For A Home Electrical Network: 6 A, 10 A, 16 A, 20 A, 25 A, 32 A, 40 A, 50 A, 63 A. Limit Switching Capacity (Breaking Capacity): Short-Circuit Current That The Machine Can Withstand And Break Without Damaging The Contacts. In Everyday Life They Use 4.5 Ka, 6 Ka And 10 Ka. Current Limiting Class: Arc Extinguishing Time (Class 3 Is Considered The Safest And Fastest). Institution No. 39, Luminous Flux (Brightness): Measured In Lumens (Lm). Determines How Much Light The Lamp Produces. For Example, A 10 W Lamp Produces About 800–900 Lumens, Which Is Equivalent To A 75–100 W Incandescent Lamp. Wattage: Electricity Consumption In Watts (W). Household Lamps Typically Range From \(3.5\) To \(15\) W. Color Temperature (Kelvin):\(2700-3000\) K: Warm, Cozy Light (Similar To Incandescent).\(4000-4500\) K: Neutral, Daylight White Light.\(6000-6500\) K: Cool White Light (With Blue Tint). Base Type: The Most Common Are E27 (Standard) And E14 (Minion). Color Rendering Index (Cri): The Higher The Value, The More Natural The Colors Of Objects Look. A Good Indicator Is Cri > 80. Pulsation Coefficient: High-Quality Lamps Have A Low Level Of Flicker (\(< 5\%\)), Invisible To The Eye. Voltage: Most Operate From A Network Of \(220\) V, But There Are Models For \(12\) V. Beam Angle: Varies From Narrow To Wide (\(120^{\Circ}-270^{\Circ}\)), Affecting On How The Room Is Lit. Institution 39, Small Led Lamps Are Energy Efficient Light Sources Ranging From \(1\) To \(10\) W, With A Brightness Of \(90\)–\(1000\) Lumens. They Are Characterized By Low Heating And A Very Long Service Life, Replacing Traditional Incandescent Lamps Of \(20\)–\(75\) W. Power: \(1\) – \(12\) W (For Small Interior And Furniture Lamps). Luminous Flux: \(90\) – \(1200\) Lumens (Lm). Efficiency: \(80\) – \(120\) Lm/W (An Excellent Indicator Of Energy Saving). Color Temperature: From Warm Light (\(2700\) K) To Cold Daylight (\(6500\) K). Service Life: \(10000\) - \(50000\) Hours Of Continuous Operation. Institution No. 39
