Here at enviro-lights, we aim to make the purchase flow as easy as possible. Below is a quick-guide to ensuring you buy the correct bulb.

Step 1 - Determine The Bulb Type

We stock a wide range of different bulb types, simply navigate through the left hand menus to find the appropriate section.

Step 2 - Select Your Fitting

Bayonet Cap: the omnipresent bayonet cap bulb or 'BC' bulb features the familiar push, twist and lock mechanism. A standard bayonet cap bulb is 22mm in diameter with two lugs to locate. A smaller bayonet cap bulb is also available which is 15mm in diameter.

Standard Bulb; BC or B22d
Smaller Bulb: SBC or B15d

Edison Screw: the 'other' omnipresent bulb is the edison screw which features a fairly self-explainatory srew fitting. The Edison or 'ES' bulb is 27mm in diameter (at the base) for the standard bulb. There are also 2 other smaller bulbs available - the small edison screw 'SES' which is 14mm in diameter and the mini edison screw 'MES' which is 10mm in diameter

Standard Bulb; ES or E27
Small Bulb: SES or E14

Halogen Light Bulbs: normally come as capsules or spotlights. The two most commonly used spotlight fittings are the push-fitting GU4 & GU5.3 and the push,twist & lock fitting GU10 bulbs. Halogen capsules are used in low voltage & childrens lighting and the fitting type is determined by the size of the gap between the two locating pins - G4 and GY6.35. The 240 voltage capsule is G9.

Strip Lights: Normally used for wall lights and similar have an S15s fitting which is 15mm in diameter.

Fluorescent Tubes: Tubes have a 2 pin fitting which is commonly available in 3 sizes, G5 or G12. These fittings are used on the T5, T8 and T12 tubes.

Compact Fluorescent Tubes: CFLs without integrated control gear generally use push-fit square or rectangular fittings. Those with integral starters use 2-pin fittings those for use with electronic control gear and/or dimmers have 4-pin connectors.
Two-pin Triple turn CFLs use the GX24d-1/2/3 fitting.
Four-pin Triple-turn CFLs use the GX24q-1/2/3/4.
2D lamps use either the GR8 (2-pin) or GR10q (4-pin) connector.

Step 3 - Select Your Wattage

Choosing the correct Wattage for your bulb is important. A Watt is a measurement of power, the higher the wattage - the more energy it uses to produce light. These days the wattage is no longer an indication of how bright a lamp will be with the birth of the energy saving lamp and even halogen lamps.

Below is a chart that shows the correspondance between the old incadescent bulbs and the latest energy saving bulbs. (information taken from the energy saving trust).

StandardEnergy Saver
25W6W
40W8-11W
60W13-18W
100W20-25W
150W28-35W
200W38-45W

Step 4 - Choose your Finish

When you have the correct bulb - you may then have the option of selecting the finish to your bulb. The most common choices of finish are clear and pearl.

So if you’re looking for the latest LED light bulbs then look no further than enviro-lights.co.uk

Identifying your Light Bulbs

There’s a few important factors to consider when purchasing light bulbs both online and in a shop. The first thing you must identify is the fitting; the fitting is the part that connects the light bulb to it’s power – the most common example of this is in the classic light bulb which has a bayonet cap fitting and an Edison screw fitting. Of course, it’s never quite that straight forward and there’s many different types of fitting to light bulbs. The fitting information is normally on the bulb itself, on the bulb’s packaging or on the actually light fitting. When you have identified this, you need to identify the max wattage of the fitting, if a fitting states a max wattage of 60W then you can have any wattage of light up to (but not beyond) 60W. We also stock a new range of high efficiency halogen light bulbs that provide a high light output but with a lower power consumption. After these two important factors have been considered, you then have a choice; you can choose the brand, the colour, the finish, the beam angle, the style and the pack size of your light bulbs.

Searching & Finding made Easy

To help you find the correct light bulbs, we have made a brilliant quick search box on the left hand size. As stated in the previous paragraph, find out the fitting and wattage then use the quick search facility to drill right down to the light bulbs that you can purchase. If you can’t see what you’re looking for then give us a call as we have access to over 20,000 different light bulbs.

Multi Save Light Bulbs

Many of our competitors have failed to grasp the simple concept of pricing goods up in a manner that’s easy to understand which is why we have kept the pricing structures very simple. We don’t operate a confusing sliding scale where 8 light bulbs might cost you 87p each but 11 cost you 84p each. We have packed our light bulbs up into multi-packs and are sold as singles, 5 packs, 10 packs and 20 packs. All of our prices include VAT as well so the price you see is the price you pay – we don’t try and make our products look cheaper than they actually are.
