£10.98 £4.98


If you’re looking for a money-saving, low-energy replacement for your existing 40w incandescent bulbs, look no further.

This dimmable LED is the brightest replacement option on the market, with a powerful 470 lumens and an impressive 97% efficiency at accurately defining colour in any environment.

The energy-saving potential of this 7w bulb, compared with a traditional 40w incandescent bulb, is huge. It’s calculated to use up to 82% less energy every year of the bulb’s average lifespan of 11 years. Available with a B22 bayonet fitting, these low-energy light bulbs have been sourced and tested by Well-Lit to ensure we are supplying a cost-effective and superior product to our customers.

You’ll begin to save money and energy the minute you replace your traditional bulbs. These 7w dimmable LEDs are far more efficient and they have a much longer lifespan of approximately 25,000 hours. And don’t forget they boast a market-leading Colour Rendering Index (CRI) of 97 that lets you see your surroundings in their true colours.

All these factors combine to make this the best 7w dimmable LED bulb you can buy and the perfect solution for replacing your existing 40w incandescent lighting. If you’re still uncertain, don’t worry. All our products are tested and trusted by experts and we are so sure that you’ll be completely satisfied that we offer a full 365-day returns policy.

If LED lamps are so great, why is there so much terrible LED lighting? Are dull colours just the price you pay for lower bills?

The answer to these questions is "Colour Rendering Index".

In most LED lamps it's simply too low. At Well-lit, all our LED lamps have CRI values of 95 or above. So you can replace your halogen and incandescent lamps without losing quality of light. (And change those poor quality LEDs for something rather better.)
