110V and 240V Lighting - Practical Differences and Applications

110V Lighting:

110V lighting products are most commonly used on construction sites, where lighting may need to be run from generators or 110V transformers due to a lack of mains power.

The range of 110 volt lighting available is always increasing as companies like Red Arrow continue to bring products to the UK market. They include portable floodlights, work lights, festoon kits and more to facilitate temporary site lighting setups.

Pros:
Safer operating voltage reduces risk of electric shock.

Often meets site regulations more easily.

Suited to robust site conditions and typically designed for heavy-duty use - perfect for the UK weather all year round!

Cons:

Requires a 110V transformer if only a standard 240V mains supply is available (which may increase setup costs and complexity).

Less variety of retail options compared to standard 240V fittings (specialist suppliers usually required).

May be less energy-efficient or produce less luminosity for the same wattage compared to some 240V products, though technology variations (like LED) have made this "cons" much less impactful.

240V Lighting:

The vast majority of indoor lighting, retail lighting, and domestic lighting in the UK runs off the mains supply (240V)

Fixed external lighting, such as floodlights on the exterior of buildings, usually run off a 240V supply too.

Pros:

Widely available and familiar to most tradespeople and end-users.

Larger range of products and accessories in standard DIY stores and online.

No need for additional transformers or specialist equipment in typical domestic or commercial settings.

Cons:

Higher shock risk if used in environments where cables could be damaged (e.g. on busy construction sites).

Must be installed with proper circuit protection (RCD/MCB) and must comply with UK wiring regulations.

More stringent safety protocols on worksites (e.g., ensuring cables are never compromised).
