Description
This is a 5.4W LED reflector lamp in the R63 size, with an E27 screw cap and a white diffused face that spreads light forward rather than pinching it into a tight spot. It puts out 600 lumens at 2700K, which is the warm white end of the scale, and the pack rates it as a stand in for a 50W filament reflector. The number in R63 is the width of the front face in millimetres, so the glass measures 63mm across, and the pack gives the overall length as 102mm. Each box holds two lamps.
Reflector lamps belong in fittings that want their light aimed: open downlighters and recessed ceiling cans, angled spotlights on a track, and over counter fittings in a kitchen. Before ordering, take the old lamp out and measure the face across, because R50, R63 and R80 are not interchangeable in a close fitting aperture. Check the cap as well: E27, also written ES or Edison screw, screws in clockwise, so if your old lamp pushes in and twists a quarter turn, it is a bayonet cap and this will not fit.
The pack marks the lamp non-dimmable, so it wants a plain wall switch; leave dimmer and smart controller circuits to a lamp that states dimming on the box. The energy rating is E, and the pack claims up to 90% less energy than the filament lamp it replaces, along with a life of up to 15 years. One unit of this listing is a box of two lamps, and the minimum order is 5, sold in multiples of 5, so the smallest purchase brings ten lamps in five boxes: sensible if you have a run of spots to change at once, or want spares on the shelf.

Frequently Asked
Will this fit a standard screw cap holder?
It fits a holder that takes an E27 large Edison screw lamp. E27 is the wider of the two common screw caps, around 27mm across the thread, so compare it with the old lamp first.
How do I know whether I need R63 rather than R50 or R80?
Measure the widest part of the old lamp's face. The number is that diameter in millimetres, so this one measures 63mm across and sits between the two other common reflector sizes.
Can I put it on a dimmer switch?
No. The pack marks this lamp non-dimmable, so it wants a plain on and off switch; a dimmer or smart controller calls for a lamp that prints dimming support on the box.
Is 600 lumens enough to replace a 50W reflector?
The pack rates it as a 50W equivalent, and 600 lumens from 5.4W is in the right region for that. Over a worktop it reads as a bright, warm pool of light.
What does 2700K look like in a room?
2700K is warm white, close to the yellow light of an old filament lamp. It suits wood, brick and warm paint, and feels softer in the evening than a 4000K lamp.
Is an IP rating printed on the pack?
No figure is given for this lamp. The manufacturer does not state an IP rating, so use it in ordinary indoor fittings in dry rooms of the house.
