30pcs 12 Volt 3mm Warm White LED Lights Emitting Diodes Pre Wired 7.9 inch DC 12v LED Light Clear Lens Small LED Lamps

Excellent price on slow fade RGB 5 mm LEDs. I'm using these to repair some of my solar yard bling that uses these color changing LEDs. Speed-wise these slowly cycle through 7 different colors. They are very bright. Mfg quality is good.

Awesome little lights for my model RR. I tested them up to 36V! Wow! All were well assembled and ready to use.

For those doing 3D resin printing, with 405nm resin, I can confirm that the UV 5mm does work to cure the inside of resin prints. An important step to prevent liquid resin from reacting with the outer shell of cured resin and resulting in a physical failure of the model. The two cracked models show what happens if you don't cure the inside of the prints. To test, I dipped a mini in the resin vat, let some resin drop on the tray and then set up the LEDs near the mini and the puddle. They were both non-tacky within 5 minutes. For connections, these LEDs already have a resistor and I bought the following power supply which has an adaptor with screws for bare end wires. I twisted the groups of wires and put them in the adaptor. Plugged in the adaptor and I am set to cure inside models. No soldering, as you will see if you YouTube "resin curing snake". I only put in 5, but it's a 1A adaptor and the LEDs only use 20mA so you could attach a lot of them.Power supply:https://www.amazon.com/dp/B07C75RT38?ref=ppx_yo2ov_dt_b_fed_asin_titleHappy Printing!

I think these are a good value but a little too white for my application.

So far looks great on my wash and cure station. Looking to print something very soon to see how well they actually care but all the lights work and easy to wire up.

Buy them. They are awesome and reliable!

Used then on a popsicle stick ferris wheel and they worked great.

Super bright quality light.
