## FAQs

**What is the formula for calculating lighting?** The formula for calculating lighting is:

**Total Lumens = Area (in square meters) × Desired Illuminance (in lux)**

**How do I calculate how many light fittings I need?** To calculate how many light fittings you need, divide the total lumens required by the lumens output of each light fitting you plan to use.

**How do I figure out how much light I need in my room?** You can figure out how much light you need in your room by considering factors such as the room’s size, purpose, and personal preference. A common recommendation is around 10-20 lumens per square foot for general lighting.

**How much lighting do I need per square meter?** The amount of lighting needed per square meter depends on the room’s function and personal preference. For general lighting, around 100-300 lux is often recommended.

**How many lights do you need per square meter?** The number of lights needed per square meter depends on factors such as the type of lights used, their output, and the desired illumination level. It varies case by case.

**How do you calculate LED lights?** LED lights are calculated using the same formula as other types of lights:

**Total Lumens = Area (in square meters) × Desired Illuminance (in lux)**

**What is the rule for light fixture size?** The rule of thumb for light fixture size is to choose a fixture that complements the size of the room. For example, larger rooms may require multiple fixtures or larger fixtures for adequate lighting.

**How do you calculate fittings?** To calculate fittings, you need to determine the total lumens required for your space and then divide by the lumens output of each fitting.

**How do I choose a fixture size?** Choose a fixture size that fits the scale of your room. Larger rooms generally require larger fixtures, while smaller rooms may be adequately lit with smaller fixtures.

**How much light do I need for a 12×12 room?** For a 12×12 room, you would need around 144-288 square feet of lighting, depending on factors such as the room’s function and personal preference.

**How many downlights do I need calculator UK?** The number of downlights needed in the UK depends on factors such as room size, ceiling height, and desired illumination level. There are various online calculators available to help determine the optimal number.

**How much light do I need in a room UK?** The amount of light needed in a room in the UK varies depending on factors such as room size, function, and personal preference. A common recommendation is around 100-300 lux for general lighting.

**Can you have too many downlights?** Yes, having too many downlights can lead to excessive brightness and glare, which may be uncomfortable or unpleasant. It’s important to strike a balance between adequate lighting and avoiding over-illumination.

**How do you calculate LEDs per meter?** To calculate LEDs per meter, you need to consider factors such as the LED strip’s length, the number of LEDs per meter in the strip, and the desired brightness level.

**How many watts per square meter for lighting?** The number of watts per square meter for lighting varies depending on factors such as the type of lighting used and the desired illumination level. Typically, for general lighting, around 10-30 watts per square meter is common.

**How much does it cost to run a 60W light bulb for 24 hours UK?** Assuming an average electricity cost of around £0.14 per kWh in the UK, running a 60W light bulb for 24 hours would cost approximately £0.20.

**What is the rule of thumb for lighting fixtures?** The rule of thumb for lighting fixtures is to choose fixtures that complement the room’s size and function. Larger rooms may require multiple fixtures or larger fixtures for adequate lighting.

**What is the British standard for lighting design?** The British standard for lighting design is BS EN 12464-1, which provides guidance on the lighting requirements for indoor workspaces.

**What is the rule for lighting?** The rule for lighting is to provide adequate illumination for the intended use of the space while considering factors such as energy efficiency, visual comfort, and aesthetics.

**How are fittings sized?** Fittings are sized based on factors such as their dimensions, lumens output, and compatibility with the space they’re intended for.

**What is pipe calculation?** Pipe calculation refers to the process of determining the appropriate size, length, and specifications for piping systems, often used in plumbing and HVAC applications.

**How big is an fittings?** AN fittings come in various sizes, typically ranging from AN-4 to AN-20, with the number indicating the diameter of the fitting in sixteenths of an inch. For example, AN-4 fittings have a 1/4 inch diameter.
