- Reviewed in Canada on February 22, 2022Verified PurchaseA bit deceived because the different colors do not have the same intensity. See pictures of a setup with a 12v supply and 2 series of 5 LEDs. At the left, with a 10K series resistors (I=1mA). At the right with a 1K series resistor (I=10mA). While the white is super bright, the blue and red are normal, the yellow is weaker and the green is very dim.

- Reviewed in Canada on August 26, 2021Verified PurchaseThe media could not be loaded.
Easy to use, and so simple for the kids to experiment with, without injury, obviously, keep and eye on the projects, but they can do them for themselves!
Can’t wait to come up with new ideas, as we have many bulbs and a large roll of copper tape to go along with it all!
Excellent product!

5.0 out of 5 stars All 100 Tested Good
Verified PurchaseThe voltage specs given by the vender is almost useless. It's the max current rating that matters and I didn't see a max current rating. All 100 Tested Good. The LED drops about 2 volts depending on the type of LED. Using a 12 VDC source and a 2.7K resistor that gave about 3.7 mA through the LED. My guess is that the max mA is about 20 mA. I wouldn't run more than 15 mA through the LED and 10 mA is plenty. As long as this parameter is obeyed, the LED should last years. Maybe decades. Maybe centuries. Who knows.

1.0 out of 5 stars Only blue and white LED’s work. Dangerous product
Verified PurchaseEvery green, red and yellow LED couldn’t take the power and exploded, dangerous product. I only wanted the green LED’s now have to buy more elsewhere.
