Frequently asked questions about the Electrical installation and lighting category
Electrical installation and lighting — what products does this category include?
Electrical installation and lighting covers a wide range of products: luminaires, light sources, electrical extension cords, switches and motion detectors, batteries and flashlights, panels and components, and cables with accessories. The range includes LED bulbs, indoor/outdoor fixtures, sockets and mounting boxes for residential and commercial installations.
How to choose a living room light fixture — which specs matter?
Choose a fixture by lumens (2,000–4,000 lm recommended for living rooms), colour temperature (2700–3000K for warm ambience), and IP rating (IP20 for indoor). Check the bulb base (E27, GU10), dimmability, and fixture dimensions to suit ceiling height and room size.
Should I choose LED bulbs over traditional ones — reasons?
LED bulbs are more energy‑efficient and longer‑lasting than incandescent or halogen bulbs. Choose LEDs based on lumens (light output), colour temperature (around 3000K for warm light) and the correct base (E27, G4) to match your fixtures.
How to choose cable and accessories for internal wiring — cross‑section and material?
Select cable cross‑section by load: typically 1.5 mm² for lighting circuits and 2.5 mm² for sockets; copper conductors are preferred for conductivity. Also consider insulation type, fire rating, and compatibility with junction boxes and connectors.
What's the difference between wall and pendant lights and where to use them?
Wall lights (sconces) provide directed or ambient lighting for hallways, accents and bedside areas; pendant lights suit general illumination and focal styling over dining tables or kitchen islands. Use pendants where ceiling height allows, and wall lights for space‑saving or localized lighting.
What specs to check for outdoor lights for a terrace or façade?
Check the IP rating (IP65+ for water and dust protection), lumen output suited to the area, and colour temperature (3000–4000K for warm/neutral light). Also verify durable housing material (aluminium or corrosion‑resistant plastic) and if motion or timing sensors are required.
What's the difference between earthed and non‑earthed sockets — when to use earthed?
Earthed sockets protect against leakage currents and are required for high‑power appliances like washing machines and cookers. Choose earthed outlets with child protection and suitable mounting for safety and plug compatibility.
What types of switches and motion sensors suit corridors and outdoor lighting?
For corridors use touch or mechanical switches with indicator lights and group control; motion sensors for indoors should have short delay and adjustable sensitivity. For outdoor lighting choose sensors with wide coverage, IP65 protection, and adjustable time and sensitivity settings.
How to choose a desk lamp for a workspace — brightness, colour and mounting?
Choose 400–800 lm for a desk lamp, colour temperature 3000–4000K for neutral light, and even diffusion. Prefer lamps with a flexible arm or clamp mounting, adjustable brightness and anti‑glare features to reduce eye strain.
Which batteries and flashlights suit long trips and emergencies?
For long trips choose rechargeable or battery flashlights with lithium‑ion cells (≥2000 mAh) and multiple modes (low/medium/boost). Check water resistance (IPX4+), a durable aluminium body and USB charging for convenience.
