Frequently asked questions about the Compact lamps category
Compact lamps — what are they and where are they used?
Compact lamps are compact fluorescent lamps (CFL) that deliver bright light with low energy consumption and long life. They are used in homes, offices and commercial spaces; our range includes spiral lamps, double-tube types and various bases (G24, G23, 2G11, etc.).
What is the difference between compact fluorescent (CFL) and compact LED lamps?
CFLs use gas-discharge technology and can have slower warm-up, while compact LED lamps provide instant light, higher efficiency and longer life. Our range includes OSRAM and LED models with various lumen outputs (600–1100 lm) and base types.
What bases (caps) do compact lamps have and how to choose for a fixture?
Common bases in this category are G24Q, G24D, G23, 2G11 and 2G7; product titles show wattage and base (e.g. OSRAM 7W G24Q-2). Choose a lamp with the same base and operating voltage (230V or 24V) as your fixture.
What wattage and lumen output should I choose for a room?
For general lighting in living spaces, 7–18W lamps with 700–1800 lm are suitable. Our range includes models from about 600 to 1100 lm (e.g. OSRAM 7W 700 lm and OSRAM 10W 1100 lm); consider room size and purpose when choosing.
What do the markings 830, 840, 827 mean on lamps?
These codes indicate colour temperature: 830 = 3000K warm white, 840 = 4000K neutral white, 827 = 2700K very warm. Choose 827–830 for cosy home lighting and 840 for work areas.
Can compact lamps replace old fluorescent tubes?
Often yes, but match the base and dimensions: compact lamps come as spiral or double-tube types for the same holders (G24, 2G11 etc.). Check compatibility with your fixture's ballast before replacing.
What do 230V and 24V mean in a lamp description?
They indicate the operating voltage: 230V is for mains supply, 24V for low-voltage systems (e.g. specialised fixtures). Fit the lamp only into a fixture with the correct voltage.
What is the lifespan of compact lamps and does brand matter?
Compact lamps generally last longer than incandescent bulbs; reputable brands (Philips, Osram, GE) often offer longer life due to better components and stable light output. Refer to product specifications for exact performance figures when choosing.
Do compact lamps come with emergency power or built-in ballast?
There are models marked EM (emergency) and with built-in electronic ballasts, e.g. OSRAM DULUX LED EMG24D-2, which include emergency functionality and compatibility with existing gear. Look for EM in the product name and compatibility notes.
What are compact LED H7 lamps and do they fit my headlight?
H7 usually refers to automotive halogen/LED headlight bulbs, whereas our category focuses on compact CFL/lamps with bases like G24, G23. For H7 replacements use dedicated automotive LED bulbs, not household compact lamps.
How to dispose of used compact fluorescent lamps?
CFLs contain a small amount of mercury, so used lamps should be taken to recycling centres or designated collection points. Do not dispose of them in household waste; follow local disposal regulations.
