Browse Forums Lighting + Lighting Design 1 Mar 27, 2011 12:13 pm Hi I am trying to figure our what we need - warm light or cool light - we currently have standard halogen downlights. Would I be correct in assuming warm white in all general areas and cool white in functional areas etc kitchen, bathroom, hallway ? Is there much difference between the two, does anyone have the brightgreen ones? Thanks renobeginner Re: LED brightgreen etc downlight - warm light v cool white 2Mar 29, 2011 8:45 am Personally as a male I would be using what you have suggested, but I have found clients with cool white in bathrooms can affect what makeup looks like, in most cases the cool white will wash out more color on your face than the warm white (of course I do not have any problems with males wearing makeup ). As halogens were always a warm white personally I don't really see the need for cool white. The areas that I can see benefit are desk lamps where the white light would help contrast black text in an off-white newspaper. Re: LED brightgreen etc downlight - warm light v cool white 4Mar 30, 2011 12:13 am Just from a technical viewpoint.......... The "colour" of the sun, on a cloudless day, somewhere around the middle of the day, depending on your precise location, time of day, time of year etc....... Is somewhere around 5,200K - 5,600K, so there may be some validity in suggesting that bathroom lights where the ladies (or men t_w ) put on their makeup should actually be Cool White (Brightgreens CW are 5,000K, their WW are 3,000K) which would give them a more accurate representation of what their makeup colours will look like outside ........ Just a thought ............. P_D .

These days the CRI of any LED should (I use that fairly liberally in our current market) be over 80 (halogens are near 100) but you will find that warm white (3000k) products are usually higher CRI than cool white (5000k) giving the better color reproduction. In the future we should see the CRI of both colors increasing in which case the 5000k would be a better option as you have mentioned.

Umm....Yeah, That's actually a fair call too Additional info not previously disclosed...As a photographer my (all decent) flashes have a temperature of 5,600K (plus or minus not too much, depending on their quality, love my Elinchroms ) so I'm looking for my (my models ) make-up lights to be around the same temperature, so that what they see when the MUA does their makeup is what the camera sees with the strobes....... Having joined this Forum as we're building a new house (with studio), we've not yet got the LED's, but I "assumed" that they (5,000K) would be what I'd be using, never even considered the CRI factor ...Looks for Facepalm emoticon !! *Rushes off to check CRI of LED's Vs incadescent Vs WW fluros !!!

Just ask for NATA/Independent testing results, if a company wont spend a couple of thousand on testing their product they cant expect customers to swallow their fictional specs. Re: LED brightgreen etc downlight - warm light v cool white 10May 24, 2012 2:06 pm I went to the DesignEX expo in Sydney last week and saw a very interesting product at the Brightgreen stand. It was a wall mounted touchplate that you could use to control the colour temperature of their lights, you could swipe your finger across to change the colour temperature. you could also use it to dim I think. I can't find any more info on it now though. Was anyone else there/know anything about this technology? It could solve warm white V cool white dilemmas. Hi - thanks for your reply. Yes I think 'Ill go for whitish with very speckly bits rather than pure white something like this. PS was actually 2008 I built the… 2 11633 That was always going to be a challenge and a test of patience. Full marks to your mate. Did you discuss the wet area near the trampoline? 16 17287 |
