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

I use these EDGELEC 12V 3 mm UV LEDs to cure inside my resin models, and the built-in resistor makes everything so much simpler (no extra wiring hassle). They’re small but bright enough for hobby work and do exactly what I need. Definitely a good pick if you’re doing resin printing and want something reliable and plug-and-play. Remember to buy an 12V DC adapter

nice like em ~ worked perfect ~ purple and black with ultraviolet leds ! 5 stars ~ great value

Great quality and quantity for price will be purchasing again.

I got these UV LEDs for curing 3D resin prints, they work perfect for that job. They are small enough to easily fit inside most drain hole in the print. They are also powerful enough to cure resin in about 10 seconds. The leads are pre-tinned and the resistor is pre-installed. I highly recommend these for anyone working with 3D resin prints. Get yourself a 12v 2A power supply off Amazon with the screw on connector and you don't even need to do any soldering.

Why did you pick this product vs others?: Perfect for resin printing. Cures resin fast, I use it to make sure the inside of hollow models are fully cured.
