RetroLED B22 4W LED Filament Radio Valve Bulb Amber (Warm White 2700K) Description

Fans of retro styling will absolutely adore this wonderful B22 4W Filament Radio Valve Bulb from Mirrorstone because its design will immediately transport them back to the golden age of radio.

This wonderful throwback to an earlier age is actually an old radio valve style bulb that houses an LED filament, meaning that it embodies both the classic look and the superb energy efficiency that only LEDs can provide.

It features an amber coloured glass casing that’s strikingly similar to that used in vintage bulbs and, as such, it will be the perfect complement to any steampunk, utilitarian or industrial type of open light fitting you may have.

It’s available in a warm white (3000K) colour temperature which makes it ideal to provide relaxing mood lighting that will be great for living room illumination but also for bars and restaurants too.

Introducing RetroLED

The RetroLED of amber light bulbs have had their makeup completely revamped. With greater heat dissipation than ever before, these bulbs will enjoy greater lifespans. The energy-efficiency is greater than ever, so look forward to those lower costs. The retro amber finish has been retooled to offer a brighter light, whilst retaining that old-style glow.

LED Efficiency As Standard

LED light bulbs of this type will save you a great deal of money on your energy bills when you use them as replacements for your old halogen and incandescent bulbs in your home.

This B22 LED filament bulb, for example, consumes just 4W of electricity yet it will generate the same number of lumens as a 40W traditional bulb, making it 10 x less power thirsty.

Like all LEDs it’s manufactured using 100% recyclable materials and will reduce your home’s carbon footprint so it’s a whole lot more environmentally friendly than conventional bulbs like fluorescents.

This LED bulb has a 25,000 hour expected lifespan so it will outlast all other types of bulb many times over. This is also a big environmental factor, but it also means you’ll spend a lot less money on replacements over the years.

Apply our latest promo price-drop code to the contents of your shopping cart and you’ll achieve a discount of 10 – 20% on this and many other selected products.
