Lo Flexible LED Filament T45



At Well-Lit we are happy to announce the launch of an exciting new range of flexible LED filament bulbs, available in the UK for the first time.

With interior designers around the country going crazy over the latest retro industrial décor, now is the perfect time to bring you this impressive T45 tube that will add vintage elegance to your living room, office or retail setting.

If you want an option that looks beautiful and is fully dimmable and energy efficient, then this is for you. With a Colour Rendering Index (CRI) rating of 93 that won’t adversely affect the colours around you, and an anticipated lifespan of 20,000 hours, this screw fitting T45 will seamlessly replace your exiting inefficient bulbs.

At 4 watts, giving a lumen output of 170, the 2200k colour temperature will give you an ambient white light that’s warm and welcoming in any environment.

High CRI lighting
Low CRI lighting

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 93 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.)
