- One of the yellow was slightly dimmer and has a dark spot in a middle of the die, but all working well.
- Diodes are very crumbs. At a current of 0.5a blind eyes like welding.As a power source took the power supply from the computer. There is a 3,3 volt line that fits all 3 watt diodes, the damage is red. The red diode has a working voltage of 2,4 volts, so i connected the red diode to 3,3 volts through a resistor of 2 ohms. At the same time, so on the diode 470ma. for current 0.5a need a resistor 1,8 ohm.The rest of the diodes stuck directly to the 3.3 v line and everything works fine.

- All workers
- 3 cotton wool is-bright.
- Everything is ok!
- Diodes are powerful, bright, i advise the seller came 2 weeks before peter
- The order came in normal for ali term. Packing is a standard duster bag, it is a cryp bag with diodes. Everything came whole and workable. Since i make an order in this store for the third time, i was convinced of its reliability and quality of the goods, it was possible to compare with other stores with similar goods.So the seller and the product recommend.
