jojofuny 4pcs LED Filament 300mm Flexible Filament Light for Retro Bulb Repair Accessories - Warm Light Source for Indoor_Outdoor Lighting

They are bright and crazy flexible. You think they'll break.

First I think there are some misunderstandings in other reviews, which all seem to be driving these LEDs with voltage sources rather than current sources. Regulated at 100mA, they are about "night light" brightness and right around 2.6V, and they did not hit 3V until around 1A, at which point they were "light bulb" bright. Otherwise, nice warm light, light meter averaged it at around 2300K and with a positive duv (but too warm to notice), ~82 CRI, very flexible and soft. Will enjoy tinkering with this!

These are good quality for a flexible filament. The product description is not very clear the voltage and current rating of these lights. They can run on 3vdc and will need a current limiting resistor. They are very easy to break if stretched.

Just the coolest things I’ve worked with! USB supply with a 220 to 270 ohm resistor does the trick. Etsy - Enjwireart. Low voltage and safe for the coolest nightlights ever! Being able to shape these to any desired configuration is opening the creative floodgates. ;0)

Absolutely awesome. This is such a neat product to work with. LEDs were great. Super flexible. Incredibly bright. 10/10 recommend.

These work as described and are quite bright with very little current draw.

I love playing with new components for my projects. These filaments have been on my wish list for a while. they are really cool to use but they can get pretty warm.

They're fine.
