E14 (SES) LED R50 Bulb 4.2W 470lm - Warm White 2700K

This is a small reflector lamp with an E14 small Edison screw cap, drawing 4.2W and giving 470 lumens. R50 is the standard code for a reflector bulb with a 50mm face, which is why it sits in the same holders as the 40W R50 halogen the pack says it replaces. The front is a soft white opal, so the light leaves already diffused rather than as a hard point, and the shaped body behind it throws the output forward instead of scattering it inside the fitting.

Reflector lamps in this size earn their keep where the light needs to go somewhere in particular. Think spotlight bars over a kitchen worktop, small track heads, plinth and shelf lighting, glazed display cabinets and the recessed fittings often found above a stairwell. At 2700K the light reads close to old tungsten warmth, which keeps timber, brick and warm paint colours looking as they did before, so it suits living rooms, dining rooms and hallways better than a cooler white would. Check the cap before you order: E14 measures 14mm across the thread and is easy to confuse with the larger E27.

Dimming is not an option here: the specification records the lamp as non dimmable, so give it a plain on and off switch and keep it off a dimmer circuit. The energy rating is E. The retail pack prints a 15 year lifespan, based on 15,000 hours of use. Each box holds one bulb, and our minimum order is 12, sold in multiples of 12, which suits a house running the same fittings throughout or a maintenance stock. Our wider LED bulb range also covers B15 (SBC) candle and golf lamps and a GU10 spot.

Which fittings take an E14 cap?

E14 is the smaller screw cap, 14mm across the thread, used on many spot bars, track heads and small recessed fittings. Measure the thread on the old bulb if you are unsure, because the larger E27 will not fit the same holder.

Can I use it on a dimmer switch?

No. The specification records this lamp as non dimmable, so it needs a plain on and off switch. Run on a dimmer circuit a non dimming LED can flicker, buzz or fail early, so change the switch rather than the bulb.

Will it be as bright as the 40W R50 halogen it replaces?

It gives 470 lumens and the retail pack rates it as a 40W replacement, so the light output should read as familiar. The LED runs at 4.2W, which is where the saving on a long running spot circuit comes from.

What does 2700K warm white look like once it is lit?

2700K is the warm, slightly yellow white people associate with old tungsten lamps. It flatters wood, brick and warm paint, and it is the usual choice for living and dining spaces where cooler light can feel clinical.

How many bulbs do I get, and is there a minimum order?

Each box holds one bulb. Our minimum order on this listing is 12, sold in multiples of 12, so you receive twelve individually boxed lamps, which works well for a spot bar or a maintenance stock.
