E14 (SES) LED R50 Bulb 4.5W 450lm - Warm White 2700K, 2 Pack

This is a reflector lamp in the R50 size, built on an E14 small Edison screw cap and running on 4.5W of LED power for 450 lumens of output. Its retail pack rates it as a replacement for a 40W conventional reflector, which is the swap most people are making when an old mains-voltage R50 finally gives up. The light is warm white at 2700K, the softer yellow-leaning tone that reads closest to an old filament lamp, and the beam spreads across 110 degrees, so it lays down a broad pool rather than a tight circle.

E14 is the narrower of the two screw caps, 14mm across the thread against the 27mm of an E27, so the quickest check before ordering is to look at the base of the lamp you are taking out. R50 reflectors belong to small spotlight bars, track heads, shelf and display lighting, and the little directional fittings that sit over a worktop or above a run of shelving in a hallway. The 110 degree spread is wide for a reflector, which makes it more useful for general light in a small room than for picking out a single object at distance. Two lamps come in each box, so a two-head spot bar is covered by one purchase.

There is no dimming here, so put these on a plain on/off switch and keep the dimmer circuits for a lamp rated for them. The energy class is F, and the pack prints a 10 year lamp life. The IP20 rating means no protection against water, so these are for dry indoor positions only. Orders are taken in multiples of six boxes, which works out at twelve lamps, enough to do a whole run of track heads and keep a couple back as spares. It sits alongside our wider range of LED candle and golf bulbs in warm white, cool white and daylight.

Will this fit my existing R50 spotlight?

It carries an E14 small Edison screw cap, so it suits any R50 holder with a 14mm screw thread. Check the base of the lamp you are removing first, as some reflector fittings take the larger E27 instead.

How does 450 lumens compare with the 40W reflector it replaces?

The pack rates this lamp as a 40W conventional equivalent, so the light level in the room should feel familiar while the load on the circuit drops to 4.5W for each lamp.

Can I put these on a dimmer switch?

No. The specification lists them as non-dimmable, so they should be wired to a standard on/off switch rather than to a dimmer circuit or an electronic dimming module.

What does a 110 degree beam angle look like in the room?

That is a wide spread for a reflector lamp. Expect a broad, soft pool of light on the surface below rather than a sharply edged spot, which suits shelving and general use.

How many lamps do I receive, and what is the smallest order?

Each box holds two lamps. The minimum order is six boxes, sold in multiples of six, so the smallest purchase brings you twelve lamps in total.

Will it run on a normal UK supply?

Yes. It is rated for 220 to 240 volts, the standard UK mains range, and needs no separate driver or transformer because the electronics sit inside the lamp itself.
