New type of E27 MCOB Led Bulb

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.

Also, we all have accents. Big Smile Hat

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.

Watch the last minute of the youtube clip! Saves you with empathy from watching him trying to stick a knife thru his hand for most of it. I think his accent ads color to the queens English we try to use here.

The design looks more open but the concept is the same as that aircooled Cree bulb, so it is not really new.

For 120V version,maybe not safe.

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 Smile

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:

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.

Good to see that they seem to be a good product. I have 8 on the way (4 warm white and 4 cool white). Hopefully they should arrive tomorrow or next week as they have been shipped over a month ago.

I like the design of these bulbs, but my concern is due to the vented aspect of these dust will build up on the glass plate over time and there is no easy way to clean them. I guess you could blow compressed air into the vents?

You could probably do that, but it might just create ‘dust bunnies’ which would be more aggravating. Maybe spray a little electronics cleaner into the bulb to wet the dust, then blow it out with compressed air? Or, just make sure it is installed inside a fairly closed light fixture.

I like that COG design. Can’t wait till it evolves into nice looking bulbs. Certainly does not need to have the traditional A60 shape anymore.
I have just received a few of the retro filament style WW COB LED inside glass bulb for a fixture I am repurposing. A60 and some ST64 versions in 6W and 8W.
One 6W A60 fizzled when I hit the switch… broke the glass and saved the COB strips. Threw the rest away. Good I ordered an extra.

Nice find, thank you.

I’ve been wondering if the audio stream on these videos could be routed through a Google Voice phone to get a transcript.

Searched for mcob on our forum and found nothing. Embarassing and scandalous so I changed the titel on this thread.

For those of you in the USA, those new type of bulbs are being sold at Home Depot. They came out on Black Friday. A box of 10 is priced at $19.88.
They didn’t sell, so the price is being reduced. So far I have seen them as low at $15.00. I am thinking they will go even lower.
They are being sold as “rough service bulbs”
