    Smart lightbulb LED runs at 37 volts?

    I'm thinking it's gotta be the Blue LEDs they used. It seems to happen eventually to all of my bulbs after a couple of months. I'd reckon it's something like this, where they have to order a batch for a run...

    Smart lightbulb LED runs at 37 volts?

    What to you mean by those dangers? Is it if you touch those 154vdc leads by hand? Or can it transfer through the DMM somehow and do something? Can I wear like rubber gloves or something as a precaution? I've had limited experience with low voltage electronics, but I've never worked with...

    Smart lightbulb LED runs at 37 volts?

    I decided to open up and probe one which doesn't flicker and I get: Blue: 18v - 34v The low range is actually fairly large from 16v-18v, depending on the specific SMD. Is this an indication of current control?

    Smart lightbulb LED runs at 37 volts?

    OK, so I actually blew that WiFi RGB bulb away while testing it. lol It's OK, I just so happen to have another with really bad Blue flickering and opened it. I think it's a manufacturing batch problem. And I probed the different color SMD's with a multimeter and found these voltage ranges at...

    Smart lightbulb LED runs at 37 volts?

    Hi, I was puzzled by this finding. I opened the cap of a smart LED light bulb and probed the individual SMD LEDs. It seems to go up to 37 volts at max brightness. This is on the color LEDs as well. I was thinking of replacing one of the colors because it was flashing. It looks like LEDs are...

    What is MagLite Multi-Mode?

    What's wrong with the "bulb drop-ins"? Does it go bad because it doesn't have that heat sink if you run it too long at > 300 lumens?

    What is MagLite Multi-Mode?

    I just cleaned out an old "alkalined Mag". What you can do (in my model at least), is: 1. Remove the rubber button cover. 2. Use a small Allen wrench to insert into the button hole and loosen the setscrew holding the bulb assembly in place. 3. Pry out the retaining ring in front of the...

    Duracells alkalines seem to leak often

    Looks like high drain application if it leaks in a few weeks after he uses it. Maybe heat damage? I've seen ppl take them out of smoke alarms for cooking and forget to put them back in for a while all the time and they don't leak cuz of that. But the problem with rechargeables anyways, is the...

    Duracells alkalines seem to leak often

    I just dug up a box of Duracell Procell 9 Volts cuz one of my smoke alarms needed one. There were 7 dated March 2015. One was 0.11 V and another was like 7.0 V. The 0.11V leaked!!! They each had plastic terminal covers so a short was unlikely. There were 10 originally so ASSUMING that the...

    Duracells alkalines seem to leak often

    Well, I just found this...where it appears that leaking Duracell is a common complaint. So maybe they changed their manufacturing plant recently? China? Who knows. So it doesn't look like just a bad batch and anecdotal. Unless the bad batch was the supply for the past few years. lol...

    Duracells alkalines seem to leak often

    Hi, Just wondering if anyone else experiences this. It seems for the past couple of years, i've noticed that my batteries (AA in this case) seems to leak a lot. Then it occured to me, it's mostly a Duracell. Not just mine, but I noticed it when changing batteries for someone. I've used a mix...

    Is 200 lumens "dangerous"?

    Well, for normal ppl (not "flashaholics" :P) the flashlight isn't an everyday tool especially if you live in a somewhat urbanized area and power outages are like a wonder. Most parents don't "teach the kids how to use powerful flashlights" or whatever. And many parents don't even care if they...
