On the 26th to 28th of February this year the Bristol Marriott hotel hosts the biggest Hifi and AV show. The Bristol Sound and Vision Show draws AV and Hifi enthusiasts from all over the UK.

This year the Sound and Vision Bristol Show is expected to feature over 200 brands, including Yamaha, KEF, Sony, Monitor Audio, Dali, Spectral, Atacama and Sennheiser to name a few.Bristol Show offers the visitors an exclusive peek at new models giving them the opportunity to test and trial them first hand and give positive or negative feedback directly to the manufactures.Nowhere in the country has this many brands under one roof at the same time, so the Bristol show also gives the attendees a great chance to compare other models side by side.

Many retailers like Sound and Vision, Digital Direct and HiFiBitz travel to the show to gain new accounts, see the products before they are launched so they know what they are selling and out of general interest.The show lasts 3 days, from the 26th to 28th of February, in that time the show is expected to see well over 5000 people come through the doors. If you don’t like crowds, maybe the Bristol show is not for you, so why not visits your local AV and Hifi retailer like Sound and Vision. Sound and Vision have electrical shops in Bolton and Leeds, and have accounts with over 150 brands most of which are exhibiting at the show. In the Sound and Vision shops there are over 200 products on display and are available for testing.

An LED lamp uses light-emitting diodes instead of electrical filaments or gas as the source for illumination. The lamps normally consist of clusters of LEDs within a suitable housing and come in many different shapes, sizes and cap types that can fit directly into the lamp holders of the lamps they are replacing.

LEDs first became available in the 1960s and by the 1970s were being used in a wide range of equipment, however, these early LEDs only had a very low output and were useless for general lighting but were used widely as types of indicator.

To start with they came only in colours (blue, yellow, green, red & orange.) It was only in 1993 that the first white LED light was made by combining the lights that were the colour of the spectrum.

Older light bulbs like the ones still used in homes around the world have a very short life compared to LED lamps, and run on a much higher wattage, making LED lamps more cost effective in an energy efficiency sense, in terms of lifespan, and durability as there’s no filament or tube to break.
