Really cool looking LED "filament" light bulbs

Just came across these on aliexpress while on my dinner break. How cool are these

Bang

those are pretty cool indeed. And I am thinking of buying one.

Does anyone know a thing or two about the safety of these bulbs, after all they run on 220V.

The old incandescent bulb is inherently safe: if anything goes wrong the filament blows and the circuit is broken, and there's no flammable materials involved in there. With led lamps this is not neccessarily the case, that is why I only buy quality brands like Philips and Osram.

How about these?

I wonder how those LED’s are connected together. If one chip goes out, does it put out the whole bulb or one strip in the bulb or what? I’d like to try some of these at my house! I’m gonna have to research this.

Fabulous heatsink.

Got these from BG. They’re great. $4. They sell here for about $10-$15!!! E27 Incandescent Bulb 40W 220V Retro Industry Edison Style sold out-arrival notice-arrival notice

Ummm… Those are incandescent. :frowning:

LED filament bulb. A google search provides many and in 110v or 220v.

I did a review of the LEDisong filaments bulb,
It was actually pretty good. Great efficiency and good CRI. It was expensive however and I don’t know how long the filaments will last.

My understanding is that they are big long LEDs (with phosphor coating) wrapped around a metal conductor. As opposed to be being lots of little LEDs in a string. I could be wrong however. I quizzed the supplier, but they didn’t seem to know exactly how they worked either. They still have a driver / DC transformer built into the base of the globe however.

Thanks for the information. So how do you assess the safety of the electronics in these bulbs in general?

(BTW, I followed the link to your website and was extremely impressed by the thorough testing that you are doing, what a great source of information!!!)

Oh man you’re an idol to me! Your website is amazing. I keep bookmarking all the bulbs you recommend. An Australian HKJ!

OOOOOOps.

They’re gorgeous, I have a thing for these old tungsten (?) lamps.

I mean wow theyre works of art. Just beautiful…

Interesting video OL, they appear to run on 150volts, that would mean fifty tiny led’s somehow connected in series on a (?)glass substrate hmm, even though he broke one of the strips apart it wasn’t very apparent quite how they are made. Yeah , plus how do you keep them cool… Some voodoo led stuff going on here methinks!.

Awesome stuff DaveO thanks for the link very imformative.

You have an awesome website. Thanks for sharing!

Still too much for me… I don’t like the look either :slight_smile: I keep buying the mexican made incandescent

If the globes fail we make a note of it. Out of the ~300 models tested, about 3 have failed in the first hour of use. A couple went up in smoke. I have made a point now of only testing new globes while I am in the same room as the globe. As I’m too scared of a globe meltdown / fire while I am out getting lunch.

I generally don’t pull the drivers apart. So I am sure there is a lot that is missed. We have been noting down if they have any of the regulatory marks (CE Mark, C-Tick, etc…), but this doesn’t count for much with the level of fraud going on. I also don’t want the legal liability of declaring a bulb safe. So I only note down the stuff that is obviously unsafe.

Hmm. Milky and forrested houses.

Sweet mother of god you tested a lot. TY for sharing that.

Two posts from two total newbies who just joined (first post for each) both from India, and not making much sense at all in the context of this thread.

Meanwhile, the LED filament lights really are cool. I wish Lowe’s would get them (for a reasonable price). I’d fill up my house with them. Did you see that they are also selling the filaments separately? Those will be super cool when they are capable of greater output.

Color me confused…How how do these guys dissipate heat?

They don't, not very well at least. But the light emitting surface is relatively large, with low light intensity / surface area, so it gets away with dissipation through the leads and through the air.
