I’m so worried about this hurricane. They’re forecasting at least a category 2-3 hurricane when it meets landfall Wednesday early morning. We’re right in the path of it.  :sadbulb:

Especially seeing the devastation from that storm that just hit all the states up north, it’s just horrible.

We did get all of the plywood on the windows this morning. And will get the smaller items put away tomorrow. I don’t know what else to do.

I’m just so sick of all these storms. Plus I don’t know how any body will afford insurance since we keep having them, now across 5 states.

We’re already getting lot of rain and wind today days ahead of the storm.

You're trying to access it via HTTPS. Try it with HTTP. Site works fine here, just not with the HTTPS security.

Though let this be a warning to always make local copies of the things you value on the internet. If you look at a catalogue, don't just view it but save it locally.

So I decided to visit James' lamptech website in order to date a lamp, and all I see is "This website is no longer available. Unfortunately the site you are looking for is unavailable at this time. This is not a server error, but an intentional closure."
Is lamptech.co.uk gone for good? It was really useful, the most useful site I've stumbled upon related to lighting!
How will I date most of my lamps now? How will I spend my time scrolling through endless pdf's of old catalogs and pictures of unique lamps?
I hope that the Internet Archive's Wayback  Machine has captured everything.
Please put the site back up again.

A wild guess it will be approximately in the middle between efficiencies of T5 13W 827 tube and the same tube, but in halo 640 or 530.

Nope, never got told that, only to not turn it on because of the reflections.

I need to figure out what the efficiency of the lamp is. Because one reason for the deprecation of halophopshate lamps, was the lower efficiency than triphosphor. I'm thinking that this may be a way to scoot the halophosphate just past the efficiency regulations.
But since it's a rare lamp, it's not easy to find such data. Nor do i know the power and efficiency thresholds of the early 2000s regulations on fluorescent lamp efficiency.

The Americans have tubes with triphosphors and halophospate blends, and produces 70% CRI.

Thanks for indulging some hoarding and publishing a spectrum of this ;) Filling the gaps in a classic rare earth spectrum likely makes color perception better, even if if overall CRI score the lamp gets is mediocre. Also, may look like an upgrade for home users habituated to '530 color. And by using half-halo mix Osram probably saved a little bit of cost, for a very price sensitive end-user home market, where even 0.5EUR for a luminaire matters.

Yeah that my guess too, this story was told to get kids to turnoff the map lights. I too, don’t like the glare that they cause in windows/windshield.
