Energy Saving GLS Light Bulbs

Energy Saving GLS Light Bulbs


The term GLS, when applied to lighting, literally means 'General Lighting Service'; the name is usually applied to an incandescent bulb with a traditional bulb shape. However the growth in popularity of power saving bulbs has meant that there are a wide range of energy efficient equivalents available.

Replacing traditional incandescent bulbs in the home or business with energy efficient bulbs is one of the easiest ways to save energy, the environment and money. The cost of electricity bills can be reduced significantly, while also knowing that a difference is being made on a larger scale.

The GLS bulb is just one type of light bulb that is now available as an energy saving bulb or CFL, (Compact Fluorescent Lamp), Up until recent times CFLs were only available in a few shapes such as the spiral shaped bulb. However, these eco friendly bulbs in their recent form are a much better product than when they were first introduced.

Many different shapes now exist, with the GLS energy saver being very popular as it can act as a direct replacement for the traditional incandescent GLS. In most households this is a change that makes sense. Some say the newer energy saver bulbs look better and add more character to certain light fittings.

Whereas the first low energy bulbs to be introduced flickered when switched on and tended to be dull due to a low Lumen value, a vast improvement has been made.GLS Light Bulbs are now available in various sizes, wattages, lumens values, bases and colour temperatures. These variations make the modern energy efficient light bulb more versatile. For example, a cosy warm white bulb with a colour temperature of about 2700 Kelvins is an ideal choice for households, whereas a daylight white bulb (6500 Kelvins) better suits an office or larger business premises,

Most GLS bulbs are available with an ES and BC base, (Edison Screw or Bayonet Cap). They are usually available in 11 watt and 15 watt options, 15 watts low energy being equivalent to around 60 watts incandescent. The Lumens value is a highly important factor, with a higher Lumen value meaning a stronger light output.
