Looks like the CFL version of the “filament” led bulbs. The tubes are super thin ! How’s the light quality?

Looks fragile.
would absolutely love to see what the color of the light looks like, this is a really neat find

Huh… That is neat. I’m very surprised to see this in the wild. I’m also unsure why this tech didn’t take off more.

leds took over too fast for ccfls to become popular in edison bulbs i guess
Edit: Tekna Nautic Caret Squirrel Cage Lamp this thing is also super expensive (89.60 usd converted), and also is 7 watts for only 350 lumens (about 25w incandescent equivalent) so basically it just wasn’t worth the cost yet and idk if there were brighter models. This particular model is from 2009 so only a few years before LEDs start getting popular.
@Storm
Yeah, an LED bulb of the equivalent wattage would be crazy bright in comparison.
These really are just architectural lighting - reserved for those who want a very particular performance and look, with efficiency being fairly far down the priority list.
Very cool though.
@Zev
Yeah i mentioned efficiency to also just explain why it wasn’t worth it over incandescent. Phosphor formulations for it at the time must have been made pretty good as well because CFLs from around that time period as well as early LEDs usually had a pink or green tinge and and still felt more like traditional fluorescent than incandescent in terms of light quality (whereas light from most modern LEDs is much harder to differentiate from incandescent) in my experience. Still a very cool bulb though, I would definitely hold on to it as it’s a neat piece of lighting history. If LEDs never took over and fluorescent lamps were still dominant, I imagine these would be quite popular today.
@Storm
To be fair I don’t think this is a particularly old bulb. NDF are I think still selling this model today. The RRP of them though (about forty quid a bulb) limits then to fairly niche markets though.
The light output is consciously very warm. It’s a bit like candlelight.
@Zev
model seems to be from 2009 which is kinda peak CFL era, before LEDs became mainstream and while CFLs (and by extension, fluorescent lighting in general) were dominating. Still though in this time period fluorescent lamps generally didn’t (and still don’t because all focus shifted to LEDs) have the color rendering to match incandescent lamps well which makes me think the price might be partly due to needing more advanced phosphors in order to more closely match the luxury of incandescent edison style bulbs. yes, the particular bulb may be newer but regular phosphors for fluorescent and LED lamps still didn’t match incandescent well until the early-mid 2010s.
Damn this is the first time I’ve been stumped in years. I’ve really never seen one of these. Sick.
Here’s some examples: https://www.cameronpeters.co.uk/blog-article/2018/3/8/understanding-nautic-from-tekna
It’s like a bunch of mini bi pins inside an S19
i’ve seen ccfl light bulbs (usually in candelabra type stuff) but edison-style filament ccfls is something else , wow this thing must have been ahead of its time
