I was wondering where 8000K fluorescent lights would be used, Because people generally do not like daylight bulbs.

I was also wondering where you could get these,especially in T8 32 watt form.

I would only get these locally, Because there is too much risk with ordering Fluorescent tunes online.

There are also higher CCT tunes available.

Osram produces these 8000K tubes, they are the Lumilux Skywhite 880 IIRC.
But they are in European standard (18W/36W/58W)

Sylvania makes F32T8 "Skywhite" 8000K lamps for the North American market. I picked up a 2-pack at Menards while traveling through Iowa. Try Kmart...I've heard they have some of the more "oddball" Sylvania lamps. I really need to check my local one...I love their F40/930 lamps. Best warm white I've ever seen!

Looks like Kmart doesn't have them. I guess the best option is to take a 1 week road trip.

I've wondered the same thing myself: What is their "Intended" use?  I've always thought it'd be neat to see a store, school, office building, factory, or some other large-scale installation lit with 8000K lamps! 

I want to get some myself but haven't yet.  Same for 7500K F40T12 lamps.  I like the really blue colors and would love to eventually light my whole house with 7500K or 8000K lamps.

You can read at James Hooker's website at "Fourth Generation - Very High CCT".

That's actually one of my favorite websites.
Yet it doesn't have much information that would be useful to me.
And how safe is ordering tubes online?

Because people generally do not like daylight bulbs.

That is not the case here in Israel :

 - If you go in the shop and ask for "36W Fluorescent lamp" (standard 4ft T8), you get it in 6500K Daylight. Not many shops stock at all anything else

 - CFLs are available in 6500K and 2700K, they are equally common on the shelf and in peep's homes

 - Most T5's used by home users are 6500K

It is sometimes claimed that in hotter countries 6500K is more preferred, maybe that is the case indeed..



Lately we have been getting some 12000K Ice White Osram T8's in 18W and 36W. Those are made in Russia, while the ordinary Daylights are from China

They look Blueish but nowhere near as Blueish as would be expected from the K rating

To date i only seen them being sold as substitute to 6500K, not as a thing of its own. Sometimes the shop owners did not even know that what the importer supplied is not the "normal white" (6500K) - in one case, i swapped a tube in the shop's ceiling to an Ice White from the stock the were selling, to show them the color difference

According to Osram catalog, the max kelvin is 880 (8000K) for Lumilux T8, and 865 for Smartlux Pro T5.

Here in Hong Kong, you can’t even find triphosphate tubes everywhere.

1. When you ask the shop keeper for a T8 fluro tube, they just ask you ‘white(/54 cool daylight) or yellow(/33 cool white, sometimes /29 warm white)?’. Technically saying, white is 3500K, while yellow is just yellow. All special colours are only ordered under request.
2. The shop owners don’t even bother to stock up triphosphate lamps, just because the cost of halophosphate lamps are a bit cheaper. For example, when you ask for a 830 tube(3000K@Ra82, WWX in USA), they usually end up giving you a 29-530(2900K@Ra50, WW in USA) and claim that they are the exact same thing.
3. The most common fluro lamp colour here is 54-765, then 33-640, 29-530 is rarely seen as they are not available everywhere, 35-535 was popular when Hong Kong was still a British colony, before 1997.

What about ordering online?
And how would you get Ice White tubes here? According to your rule that Hot Countries = Cool Tubes, Florida should be getting 14000K bulbs, But everyone is afraid of even 4000K light.

osram.com shows only stuff meant for sale in the EU. We get here stuff that is not listed there - The ordinary 6500K 36W/765 (Its not from the "Lumilux" but from "Basic" product range, intended for Asia), sometimes starters from the "Basic" range too, and now the 12000K lamps

Does anyone have a photo of 8000K or 12000K tubes? It would be good to compare them.

Regarding shipping fluorescent lamps, I can only speak of full cases, but I only had one lamp break in a case of 25. Usually online vendors have sufficient packaging for that and there are guarantees (one hopes anyways).

A room lit with 8000K would be awesome !

I can make 12000K vs 6500K
