    Hi. I am in the process of renewing my halogen lamps to LED and its not as straight forward as I had hoped!

    Looks like there are so many variables ie wattage, number of LEDs, colour shade (cool white to warm yellow), intensity (1000K, 2000k, 3000k...). Anyway got my head round most of it but am not sure as to what beam angle to go for.

    There are lots of sites that describe the beam angle ie 40o to flood the room and 25o for more of a spot. But I just wondered in your experience which looks the best. I know different situations call for different beams, but is there any you would avoid?

    I am replacing the kitchen and lounge ones. Many thanks.

    The wider the angle, the larger the spread of light, depends what you are after.
    If you wish to spread the light more evenly over the location/area or if you want to have a more direct beam.
    Totally up to you
    Unfortunately the use of down lights was not originally for the domestic sector and they were designed to highlight specific areas, rather than spread light, but they are very popular now in the domestic sector.

    If I can just cut in here- what would folks recommend for an LED GU10 these days?

    Thanks for the replies.

    I have gone for the Phillips master 7w 3000K 25o beam in the kitchen and they look really good. Has instantly given me that clean crisp light look very atmospheric. I am going to go for a wider beam in the lounge to get a bit more of a flood lit effect. Thanks

    "Atmospheric"?

    FGS man - A KITCHEN IS A PLACE OF WORK - you don't want atmospheric you want uniform and bright enough to be able to work in there.

    Do you think you'd ever get narrow beams of atmospheric light in a commercial kitchen?

    :rolleyes:

    I think he is referring to the light quality and colour, as the philips LED's are a really nice light, irrespective of your opinions on LED/Halogen spotlights

    OK - do you think that you would ever get any lighting in a working kitchen which could reasonably be described as "atmospheric"?

    I know that the term is imprecise, but if you asked a lighting designer for "atmospheric" and he delivered what was appropriate for a kitchen you would almost certainly have words with him.

    Yes, definitely. I would count most under cabinet lighting 'atmospheric' I would also describe plinth lighting as 'atmospheric'

    Plinth lighting is, admittedly designed for effect, but cabinet lighting is both atmospheric and functional. Haven't seen it much, but over cabinet lighting is also 'atmospheric'

    Can't tell me that kitchen isn't atmospheric. Just cos it ain't fluorescent doesn't mean it's not a valid method of lighting

    secure, i have used the led hut ones that state a 120 degree beam angle. I cant pretend to tell you exactly how that beam is measured in terms of lumens per degree and because of the envelope of the lamp face, i dont know how that can be acheived, but they give a more noticable ambient light than others i have used, if that is what you are after. I am not a fan of downlighters for general room lighting however.
