There are an increasing number of alternative "energy saving" lamps available. Depending on the type of lamp, the energy saving potential and type of light emitted is different - this guide provides a summary of some popular types.
The fittings themselves contain control gear which is designed to operate "pin based" fluorescent lamps. These lamps have unique lampholder types which are only suitable for the type of lamp detailed in the specification. They come in several different shapes dependant on the lamp holder.
They consume around 20% of the energy used by a conventional incandescent (GLS) lamp and have a life of between 10 and 15 times longer (dependant on specific lamps).
This type of lamp is available to suit many of the common lampholder types, (BC, ES, SES, GU10) and is suitable for use in many of the fittings. It is a fluorescent lamp, similar in operation and energy saving to the dedicated low energy lamps but with the control gear housed within the lamp itself. This allows them to be fitted in fittings designed for use with conventional GLS lamps. They are available in a variety of shapes and sizes of varying wattages. A guide for comparable wattages can be found below.
|Incandescent Lamp||Retro Fit Lamp (Self Ballasted)|
|25 Watt||57 - 7 Watt|
|40 Watt||8 - 10 Watt|
|60 Watt||11 - 14 Watt|
|75 Watt||15 - 17 Watt|
|100 Watt||18 - 22 Watt|
|150 Watt||23 - 27 Watt|
The type of light will vary dependant on the "colour temperature" of the lamp - a lamp marked 827 (or 2700k) will produce a warm light, similar in appearance to a conventional GLS whilst an 835 (3500k) will produce a colder light which may be more suitable for some contemporary fittings. Lamps with a colour temperature above 5000k are referred to as "daylight" and give excellent colour rendering suitable for task lighting.
NOTE: This type of lamp is not suitable for use on products which have touch dimmers or which are intended to be dimmed.
NOTE: Energy saving bulbs are available in the standard cap sizes to fit most light fittings (BC/B22, SBC/B15, ES/E27, SES/E14 and in GLS, candle and stick shapes), but the overall dimensions can differslightly due to the width and heigh of the tubes. It is advised to test for fit before purchase.

NOTE: Always observe the maximum wattage rating on the fitting.
A dimmer switch suitable for trailing edge (also described as phase lagging) is most likely to be compatible. This information is included in instructions for the appropriate products.
A dimmer switch suitable for inductive loads must be selected.
A dimmer switch is a third party accessory and compatibility with our products is not guaranteed. These notes are for guidance only. For further advice, please contact a qualified electrician or the manufacturer of the dimmer switch you intend to use.
DO NOT USE dimmer switches on products which contain fluorescent lamps (including fluorescent "energy saving" lamps).
Please note that buzzing from the transformer is frequently caused by the dimmer switch - this may be because the wrong type of dimmer switch has been selected but it is quite normal for there to be some buzzing from either the dimmer switch or the transformer of any item being dimmed. A slight buzz is not indicative of a problem with the fitting or dimmer, it is a normal by-product of dimming the item. A more serious buzzing is almost always a result of using an incompatible/incorrect dimmer.
|Compact Fluorescent Available with built-in ballast with ES or BC fitment for replacement of GLS bulbs. Ideal for lights that will be left on for long periods, i.e. outside, hall or porch lights.||
|Class 1 240 volt The fitting requires a connection to earth.||'FX' marked Mounting surface of fitting can exceed 90??C. Not suitable for mounting on flammable surfaces. Minimum distance from illuminated surface 0.3m. Distance depends on wattage and reflector. Usually only used for products with reflectors built in or MR16, GU10. Ensure light source is not too close to surfaces causing them to overheat.|
|Class 2 240 volt 2 core double insulated - no earth connection required.||Miniumum distance from illuminated surface - 0.3m Distance depends on wattage and reflector. Usually only used for products with reflectors built in or MR16, GU10. Ensure light source is not too close to surfaces causing them to overheat.|
|Class 3 12 volt Extra low voltage.||
||Replace broken protective glass (either round or rectangular). Some halogen and metal halide bulbs require a protective shield to offer protection should the bulb shatter. The shield must be replaced if broken to maintain security.|
|'F' marked Mounting of surface of fitting will not exceed 90??C. Suitable for mounting on flammable surfaces.||Self shield lamp Warns that the use of glass fronted MR16, GU10 or low pressure capsule lamps must be used.|
