Led strips/row of leds on a glass plate ( Edited; COB/ glass plate techology is only with the 12w bulb in the advert). Ventilation, but no heat to the socket. New tech in a bulb.
Edit; Save some time and watch the last minute! Also, only 220-240 volt bulbs.
I’m curious, but not curious enough to watch a heavily accented Scotsman take 17:24 minutes to describe it, the youtube guys need to try to trim things down for their videos.
You call that a heavy accent? Sounds light to me. I’ve heard some UK area accents that are 20 times stronger. Quite hard to understand. Though ability to understand accents seems to vary from person to person. I had a close family member who had difficulty with accents.
Hmm, that bulb is interesting.
Though I would never buy a direct-from-china brand light bulb or any AC powered device. Certainly not worth risk, not even if they gave them away for free. UL listed for me.
I’ve heard some that even their English mates couldn’t understand, this guys isn’t so bad, but over 17 minutes of it about a light bulb is more than I’m willing to sit through, I’ll wait for a print article or print review, I’m more a reader anyway.
Last minute of the video show rows of 18 leds on a glass plate,
so not the same tech as Cree bulbs?
I changed the heading and my posts to stress that they are cob.
Also should ad that he measure them to be 6W against the adverted 12W.
love the filament bulbs.
Just returned from friends, I had ordered filament bulbs for them, to replace the normal lightbulbs in a chandelier. They did not use it, the light was way too brght.
Now they do and even off the bulbs look very nice.
Have them in almost all places where the bulb can be seen.
LED filament bulbs have been available in the US at Lowes hardware stores for several months and sold under the Feit Electric brand (I bought several and returned them due to their horrible dingy yellow 2200K tint). Also, hundreds of others have been available online for at least a year.
We have a BLF member who has tested dozens of LED bulbs. To his surprise, the filament LED bulb provided the highest lumens per watt advantage above all the others. I have been using a 6 watt 540lm version for 8 hours per night for 6 months, and it has yet to show any lux degradation (verified with my lux meter). I removed the glass envelope to allow open air cooling to the emitter filaments and other tests, so it is unclear if the direct thermal path to the ambient air helps in longevity, but it certainly runs a good deal cooler while uncapped. Hopefully these will prove to be more reliable than the cheap version conventional SMD mounted LED bulbs being offered by Cree, Philips, Sylvania, Feit Electric, GE’s, etc., that have failed so many others within the fist few weeks or months of operation.
Bah! I just love his accent, I watched the 17 minutes just enjoying him speaking! I mean, if I met him in a dark alley, I’d probably turn around and run, but his voice and accent makes me think he’s a great guy to share a pint with
My favorite bigclive video is this one though:
This one is kinda fun as well, as I have received 7 of these (but euro kind, not UK) from Banggood:
Thanks. That was a great deal! I just bought a house so I am looking for these kinds of deals. if anyone stumbles across a great deal for any type LED bulb please let me know.
I see there is not much interest in new tech here. However,I bought the
bulb that the thread is all about. Two weeks before they
sent it,so probably they had to buy it from somewhere.Ordered warm white and got a cool tint. No heat/no driver in the socket so I think it is 6W(not 12W as in advert) and more than 800 lumens,ei more efficient than anything I have seen.
