E27 4W LED Filament Radio Valve Bulb Amber (Warm White 2700K) Description

The Steampunk genre is enjoying something of a renaissance right now, so what could be better to complement your retro-styled light fittings than this E27 4W LED Filament Radio Valve Bulb from Mirrorstone Lighting?

A great looking reproduction of the incandescent light bulbs of yore, this revolutionary LED bulb uses a filament for authenticity, has an eye-catching shape and boasts an amber coated glass casing to give the impression of age.

That said, however, it is every bit as energy-efficient as any other E22 bulb you care to mentions. Indeed, this 2700K warm white LED consumes a mere 4 watts of electricity yet is able to generate the same number of lumens as a 40 watt conventional bulb, meaning that it’s 90% more energy efficient.

The Advantages Of LED

Consider, therefore, the amount of money you will save when you replace all of your existing bulbs with energy-saving LEDs, and that’s without even taking into account their extremely long expected lifetime!

Yes, with a massive 25,000 hour lifespan, this bulb will outlast an incandescent bulb around 16 times over, thereby saving you a great deal on replacements, as well!

Unlike many of the light bulbs that people use in their homes, these LEDs are manufactured using 100% recyclable materials and they contain no harmful mercury vapour, so they’re a great deal better for the environment, too!

Quite aside from the savings you’ll make on your electricity bills by using these LEDs in your home, you’ll save a further 10 – 20% on the price of this bulb simply by applying our latest promotional discount code to your shopping cart at the checkout.

Any orders you place of £40.00 or more will be shipped free-of-charge, so start saving money today!

LED Lighting To Brighten Your Home

Once you begin using LEDs, you’ll never want to go back to conventional bulbs, so why not take a look at the huge selection of other E27 LED bulbs that we have on offer right now?

The E27 4W LED Filament Pear Shaped Bulbs or their companions, the Dimmable versions will look equally amazing when used in the Colonial Antique Brass Twin LED Wall Light in your bedroom or living area.
