There are four of these sticks inside the lamp

OK, went and checked. Unusually for here, my beside clip on spot lamp does use the Euro ES.
It's an Osram R63 style, 4.5W, E27 fitting and 24mA for 220V to 240V. The model might be AC02275. It's warmish 2700K (I have a scary 4300K LED stick lamp in my library, quite blue). Claims 370 lumens.
I've tried various lamps and these LED sticks are the only thing approaching halogen in pleasantness. Ones with better colour rendition (not needed for reading and unconnected to colour temperature) are less efficient, some are alleged to mix in red and cyan LEDs on the sticks to fill gaps in the spectrum. Regular LED lamps using only blue, violet or near UV chips only with a simple yellow phosphor can be any colour temperature, depending on phosphor amount, but are rubbish at the cyan part of the spectrum. |
Thank you.
Edit: your mention of Osram rang a bell and I checked my reading lamp; it has a similar Osram 2700K 4W, with LED sticks. Possibly a bit dimmer than your model (as I no longer have the box, I don't know the precise details). It's a good light, but unlit screens still don't look particularly pretty under it, imho.
