Daylight is 6500. Cool white certainly is not 4000k that would imply the 6000 range would be so blue. Granted it would look cold if one is completely used to yellow/orange bulbs.

LEDs cannot produce true 6500k with a CRI of 90.

I prefer them personally. Less light pollution and use a lot less power and need replacing less, so they don't need to be turned off so much to save money. I prefer the more natural light too, always hated the weird orange glow. There appears to be more shadow, but that's because they are brighter. Anyway, they are here to stay.

everywhere ... domestic/commercial everywhere

they will flat out just stop making them

cool white certainly is 4000k ....ive only sold about hundreds ....of thousands of the things

pop in to my shop ... ill show you the colour difference

eidted to add .... i can sell you a fully integrated (no lamp to change) LED downlight that you can choose which colour you want ...either warm white/cool white /daylight in the same fitting

i generally advise my customers that the cool white looks good in modern kitchens/bathrooms (where theres a lot of white surfaces) just makes everything look cleaner brighter and crisper

the warm whites are good for hallways bedroom living rooms..a bit more comfy and relaxing

oh behave

are they replacing them with something that has the same fitting?

i`ve got under cupboard lights in the kitchen and a gorgeous row of spots i`ve had for a decade and never used that i want to get going

yeah they will make retrofits for them ..they probably do now the under cabinet stuff might be a pain

but your down lights and stuff will just have a retro replacement ... (if you haven't already id advise changing them from halogen to LED) they'll last forever and your running costs will shrink )

If LEDs are so good why aren't they used in film studios/broadcasting suites while editing their films and content in post processing.

There is a reason why the measured colour is required and LEDs cannot deliver. http://www.cinemaquestinc.com/ive.htm

thanks panic over, not bothered about the kitchen ones they`ll be staying here when i move.

i don`t really like led light, it`s horrible for working under.

did you not read the part where i said its pretty new technology in regards to lighting ??
and i realize they have been around awhile in electronics etc

and yes they aren't used in film ...one of my client is a printer for magazines such as zoo(before they disappeared into the ether) ...they didn't use LED either (they did use daylight fluorescent though )...but once a bit more research goes into it they will use LEDs

ive seen dramatic change in the lighting industry over the 12 years ive been in it ...but the changes in led reliability/ colour rendering/ output in the past year alone has been unprecedented ive seen companies release a retro fit GU10 lamp ....and 6 months later render it obsolete as they had improved on the performance and life span in just 6 months (at no extra cost to the consumer )

Pah you just dont like change

when the old 40/60/100w incandescent become obsolete people were screaming blue murder (especially the older generations).. these new fangled compact flourescents dont give enough light blah blah ....no one likes change really...the contrators were even worse ...they were losing money on call outs to to do re-lamps as the CFLs lasted longer than incandescent

no, i`ve got some leds and they cast a really unpleasant and cold light, i don`t have the words for describing it but the field is very narrow and they make colours look flat which isn`t ideal if you`re doing anything creative.

i don`t like those curly ones either, they are very bad for my eyes but better for working under if you can set it so that you don`t catch an eyeful of the naked bulb.

what winds me up most is the other end, i`ve got loads of spares that fit nothing

sounds like you have a cool white or daylight ...try swapping for a warm white see how you get on

which ones? i didn`t know they even came in colours

We have gone completely over to LEDs in our house and would not go back now. The light is instant and if the right colour temperature bulbs are picked for the required situation they are far superior. No more of the horrible compact fluorescents that took time to reach optimum light.

with LED you generally get what you paid ...go for a good qulaity one like a BELL lighting or an osram ... id avoid scrwfix ones where you get like 10 for a fiver ... just find a a local electrical wholesaler (pm me if you want and i can offer more advice) and just tell them what ya want

Light bulb adapters

thank you, that`s very kind .

ooo that`s a handy link!! ta.

it was much more simple when you had bayonet or nothing.

I mentioned before that (by eye) the warm white LEDs I bought were virtually identical to tungstem filament lamps, which certainly puts them somewhere close to 3000K. I was surprised to see cool white as low as 4000K, though - but then again, I wouldn't expect makers of Christmas trees or LED torches to be especially bothered about adhering to strict standards.


Fair enough, but this thread started off talking about street lights. Photography / cinematography / videography are bound to demand much higher standards of colour precision than walking about without walking into bushes or tripping over the kerb!

Many Brexiters and Remainers alike will hope that leaving the EU and also the Trump US presidency will allow that to be changed. It would make a tempting 2020 UK and US General Election manifesto promise.

not sure Brexit will matter that much to be honest ,,the big four lamp manufactures will abide by European rules and regs anyway

cant buy halogens if no one is making them

I suppose if you're in the middle of nowhere in the countryside a streetlight with LED bulbs in their current state probably wouldn't be too effective, but in the area of London I live in a lot of our streetlights have been changed to LED ones and they're fine but a lot of that is down to the fact it is very built up so you have car lights, lights from shops, lights from houses etc making everywhere fairly well lit up.

I have some LED bulbs in my house and they're fine. I've not had enough time to work out if they're reducing my electricity bill by much.

Nobody has much of a clue yet what Trump will do or allow and I wouldn't be at all surprised to see timescale slippages at least. If halogens last to 2020, UK politicians might just be tempted to follow whatever the US line is at the time but we shall see.

Got them installed here but the council has done well by installing them on opposite sides of the street but placing them so that they area lit slightly overlaps so the whole road is lit.
