LED Strip Lights Compared โ 12V, 24V, 220V and Neon Flex
Learn LED strip light types in simple terms. Strip voltage and construction determine how it is powered, cut, controlled and installed. This guide includes selection checks, common mistakes and relevant Whitehouse product examples.
Quick answer: Strip voltage and construction determine how it is powered, cut, controlled and installed.
Why this matters
Customers often reach a product page after searching for one specification, but the correct result depends on how several specifications work together. Understanding the terms below helps prevent incompatible purchases, poor light quality and unnecessary replacement costs.
- Low-voltage 12V and 24V strips require a compatible driver and are common in cabinetry and detailed installations.
- 220V strips connect through purpose-designed rectifiers or power leads and can suit longer runs, but installation requirements are different.
- Neon flex uses a diffusing jacket to create a more continuous line of light.
- Single-row and double-row designs can differ in brightness, width and heat output.
How to choose the right product
- Choose voltage before selecting controllers and accessories.
- Confirm cut intervals and maximum run length.
- Use neon flex where a continuous line is more important than a slim strip.
- Plan waterproofing and end caps for outdoor-rated products.
- Have mains-voltage strip installations completed safely and according to product instructions.

Frequently asked questions
Is 220V strip brighter than 12V strip?
Voltage alone does not determine brightness; compare power per metre and lumen output.
Which strip is best under cabinets?
Low-voltage strip in an aluminium profile is often practical for detailed indoor work.
Why choose neon flex?
It produces a smoother visible line and can be easier to use in decorative contours.
