I ordered dozens of LED light bulbs from different suppliers on AliExpress. Nearly all failed within a few months, some immediately, some after a short time of operation. Failures had different causes, all ultimately due to shoddy components. I no longer have the names of the different suppliers but I would not trust any light bulb not sourced via a name brand company that enforces quality standards. This is the worst rip-off I have ever experienced.

This is really a brew thread, but I can empathize having a similar problem with 10 x 100w LED for our church. They were dying over a short period of time, finally we gave up on them spent more and got some decent replacements from local supplier.

see if you can spot the problem:

 

Can't measure greater than 100 proof alcohol?

Wrong - look at the design

Bung: The thing I noticed was that the scale wasn't linear but then found that's as it should be.

Doesnt a beers sg get heavier as it brews?

Sorry. I keep doing that. I have to learn to look before I leap.

As others have suggested, the markings are the wrong way up.

How about the Chinese characters? Are they the right way round or not?

By the looks, you can't see the reading, because it goes inside, behind the paper! LOL

Last tip; the meter rises as alchohol content rises.

Huh? Coming from the distillation world that doesn't line up with my experience. I have a hydrometer for measuring specific gravity of my wash, which goes down as the yeast consume the sugars, and I have a alcometer which sits lower as the proof increases increases in my distillate. That meter would be no use for me distilling as I'm seldom below 70% coming off the still, but it would be fine for watering down the spirits to 40% for consumption.

Hmm, I have been known to be wrong before, but look at this one, and the way the graduations are set; water at the top. Also, this meter rises when I put it in to a brew and I have ensured there are no bubbles on it:

The alchoholmeter reading of water is 0. The sg reading of a FV liquid is higher at start, but lower at end, but still higher than water right?

If I place this meter in water it reads 0. If I place it in FV/brew it rises up, past the 0 into a non reading range as the readings are above 0.

I think you are mixing up two types (which is why I have both) Looking at your scale sitting at it's highest means there is enough sugar uneaten in the wash to make 20% strength booze after the yeast have consumed it. Once they have done their thing it will drop to a lower value indicating the sugar is gone.

The device you have purchased is for measuring % ethanol vs water.
