Will you share please what and where of the video microscope? I really would like to have one if still in production 😊

A search for "LCD microscope" on Google should bring them up. There's a variety, mine's on the cheaper end.

Interesting video. One Question. Can I use the filament inside the bulb for... maybe, custom dioramas? I mean, xtract the filament for a occasionally project, or the filament inside the bulb will be ruined? Thanks.

You should pick up a few filaments to the spec that you require. I'm not sure what "the bulb" is in this context but it probably doesn't contain what you need.

I have a plastic red star Christmas tree topper that I want to convert to LEDs and fillament bulbs would be best option. I found on Amazon 3v 100mA and 12v 45mA. Does it mean the 12v runs less current and doesn’t get as hot as the 3v at 100mA? If a bulb is 60-70 lumens does it mean 5 bulbs together would be 300 lumens or still 60 lumens? I’m trying to understand how to go about it without melting my plastic tree topper.

Practically you'd probably want to just run the LEDs and see if they get hot. You can under-drive them by providing them less voltage or using inline resistance but if they're already doing some form of driving internally they may not need it. To understand how hot they'd get you'd have to know how they're being driven (i.e. how many LEDs are in series for the 12v? What's the resistance used in the 3v if any and how many LEDs ?) BigClive at kzitem.info does an astonishing number of excellent LED and lighting videos as he's a lighting-centric engineer if you want a good depth of knowledge on how power feeds LED circuits.

power=voltage x current so the 12v should run cooler.

I have 260 mm filament. Is it possible to cut it off to make a smaller piece?

Not with these. They're integrated into an assembly; although it looks like filament the LED assembly is COB and a single fragile piece.

Nice job on sharing knowledge. I was always curious on those small lights. If possible, Would you be able to share knowledge on connecting 1 to a battery with a button. I'm working with my son on a space ship and would like to use the filament light "safely" thank you be safe 👍

You would connect it in series with a button and a resistor using the appropriate voltage for your application. And make sure the wiring was of the correct gauge for the load. Adafruit has a guide with calculators up for that here: learn.adafruit.com/lets-put-leds-in-things/basic-recipe They don't mention wire gauge. But if you know the draw (which they do cover) you can punch that into any website covering the topic along with length of wire and should get the appropriate safe minimum.

Can you attach a wire to them and make the wire hot? I need to get over 200 celsius using a 3volt changer Thanks for letting me ask

You may have some confusion. These are LEDs. They are not heaters.

I believe that's covered pretty thoroughly in the video. The thumbnail, even. I'm not sure what else I can add unless you've got a more specific question.

Depending on what else I'm working on the gloves are to keep solvent off to prevent my hands reacting to it. I swear they're more sensitive to it after years of working on cars and electronics. But yea, sometimes.
