In 2005, Lights4fun brought the first battery fairy lights to the UK and ever since they've proved to be quite a find. Battery lights have evolved slightly since the early days, however much remains the same, still providing you with wonderfully easy to use lights and incredible eco-friendly benefits. We've racked our brains to give you a concise, yet really handy selection of advice and top tips to consider when buying battery lighting of any sort online. If you already know what you want then you can jump straight to our indoor battery lights section to buy.
Let's be honest here, you're never going to get the same brightness from battery lights as you would from a plug-in, mains powered light. Most battery fairy lights use either 2 or 3 AA batteries to light up to 40 LEDs comfortably. The beauty of having a battery light is the ease of use, and with 2 or 3 AA batteries you can expect up to 50 hours illumination before they will need a change. This is perfect for Christmas displays or one off events.
Battery light brightness can vary between manufacturer however as a general rule of thumb with all Lights4fun products we'd stick to this:
Most AA batteries, Energizer, Duracell etc, are 1.5 volts.
The more batteries a product takes, the brighter the bulbs will be as there is more voltage output. Our 3 x AA battery lights have 4.5 volts output and give a beautifully bright colour.
The more LEDs on a set will reduce the brightness, slightly.
At Lights4fun we ensure that all our battery lights reach a standard of optimum brightness and hours of illumination. It's all well and good having a hugely bright light output from a set but if they only last around 10 hours then you're spending more money on batteries. In order to ensure batteries are not drained too quickly we control the amount of voltage each LED uses, thus resulting in a great light output and lifespan of batteries being used. If brightness is something which you require then we would always recommending a minimum of 4.5 volt output for your application.
LEDs in daylight conditions
Battery lights always use LED bulbs. For more technical information on LEDs, see our buying guide. A common mistake is the assumption that LEDs will show brightly in daylight conditions. If you're planning on using your battery lights in brightly lit environments with sunlight or tungsten lamps above, you'll see a poor performance from your battery lights. With the limited voltage from a battery cell, it's difficult to get an LED to show brightly in these conditions. Make sure if your'e creating a display that the lighting is correct so your battery lights can be seen.
A handy benefit of LED battery lights is that they appear colourless until illuminated meaning if you don't want them showing until night time, you'll be able to hide your lights with ease.
Different colours are brighter
In the colour spectrum of LEDs you'll find that certain colours are brighter to the human eye. The most popular white, blue & greens tend to appear more piercing than those reds, ambers and yellows. This is applicable to many other lights, not just battery powered, however with the low voltage being used from battery cells, it's more apparent if you place these colours together. Our advice is to keep red separate from blue and white unless you want the stronger colours to dominate.
Without the added potential risk provided by a mains current, battery operated lights function at an extremely low voltage, meaning that even a small shock is unlikely, should the product malfunction. Superb for use indoor against fabrics, LED bulbs don't generate any heat so you can be confident about passing those health and safety regulations for venues, or just peace of mind in your home.
Whilst battery lights are hugely eco-friendly in comparison to mains powered alternatives, there is an environmental impact that lies with the consumer. The use of non-biodegradable battieres you can purchase from any supermarket have to be disposed or recycled very carefully. We'd always insist on using rechargable batteries to help the environment when using battery powered lights. If you're planning on reducing your carbon footprint then battery lights may be a superb solution with some rechargable batteries also.
