Another new twist with LED filaments. This style is designed to emulate traditional retro filament lamps with a very long LED filament that emits a very golden light.

The dimmable E14 es LED filament are strange in a touch lamps .. they start off bright and go dim for every touch, whereas the old type of bulb started off dull and go bright with every touch …. My touch lamp is 20 years old I still have the original bulb from new, it's used every night for the last 20 years. … It's lasted so long because I've only used on low .. I've heard these new type of E14 LED Filament don't last long .. thanks for posting .. 🙂
The big question is what is the gas in the bulb , and what pressure? Those LEDs need to be cool . hydrogen and helium are about 6 or 8 times more thermally conductive than heavier gasses ( air ,N2 ) increase molecular weight reduces conductivity . Convection currents in the gas will complicate things .
WORST REVIEW EVER!!!
Only joking, loved it. Thanks BC.
In Japan (with 100V mains) you'd be bang on with a single filament.
is it true that there is a thermal conductive gas in the type of led bulb featured?
Nice review of the filament LED lamp. I really like this style of lamp, looks neat whilst also being efficient.
How did you manage to convert it from E27 to B22?
8.0 degrees C ambient, my God, has anyone heard of the invention "central heating"? Or is that not available in certain parts of the UK?
Noticed that the data sheet says "Chip land"… I guess they mean GROUND. Auto-translate strikes again.
when you said lots of interesting stuff coming from china coronavirus comes to mind :-<
I don't know how I got here, but I enjoyed it regardless and the accent
I wonder if they fill any of these globes with helium. It is much better at heat transfer than air, would keep the filaments much cooler by convecting heat to the glass. Basically the opposite of the fancy double pane windows that they fill with insulating gasses.
If you break the bulb will the led still light up???
Seems that you have a lot of trust in that plug-in power meter when checking power input to these lamps. Hmm..
That audio feed back tho
Had minor seizure , still worth it 💯
