E14 (SES) LED R50 Bulb 4W 450lm - Warm White 2700K, 2 Pack

This is an R50 reflector lamp with the small E14 screw cap, often written as SES. The reflector shape puts the light forward in a cone rather than scattering it all round the fitting, which is why it is the usual choice for small spotlight bars and display fittings. It draws 4W and gives 450 lumens at 2700K, a warm white close to the colour of the old incandescent reflectors, and the pack rates it as the equivalent of a 40W bulb. Energy class is E. The pack gives the head as 50mm across and the overall length as 85mm.

R50 is the size that goes into kitchen spot bars, glass display cabinets, cooker hood housings, picture lights and small wall or ceiling spots that take a screw cap rather than a pin. If you are replacing an old halogen or incandescent R50, the swap is direct: the cap, the 50mm face and the 85mm length are the same, so nothing in the fitting needs altering. The warm 2700K tone suits living rooms, hallways and kitchens where cooler light would read as clinical, and it sits comfortably beside other warm white lamps already in the room.

There is no dimming: the pack marks the lamp non-dimmable, so pair it with a plain on and off switch and leave any dimmer circuits to a lamp rated for them. The pack states a life of up to 15 years. Each box holds two bulbs, and the listing is sold in multiples of six boxes, which works well if you are relighting a whole spot bar and want spares. We also list E27 reflectors in the larger R63 and R80 sizes, along with E14 candle bulbs in warm white and daylight, if other fittings in the same room need filling.

How do I know my fitting takes an E14 cap?

E14 is the small screw thread, around 14mm across, also called SES. Unscrew the old lamp and compare the thread before ordering.

Will it fit a 50mm spotlight housing?

The pack gives a 50mm face and an 85mm overall length, which is the standard R50 envelope, so it drops into housings built for that size.

Can I put it on a dimmer switch?

No. The pack marks this lamp non-dimmable, so use it on a plain switch; a dimmer circuit can cause flicker, buzzing or early failure.

What does 2700K warm white actually look like?

It is the soft yellow-leaning white people associate with old filament lamps, comfortable in living rooms and hallways rather than crisp and clinical.

Is an IP rating given for this lamp?

The manufacturer does not state one, so treat it as an ordinary indoor lamp and fit it only in dry, protected positions.

How many bulbs do I receive?

Each box contains two bulbs and the minimum order is six boxes, so a smallest order brings twelve lamps in total.
