    Very bright All perfect working, and of course quick delivery from DX I used 34 of these to build a diving light special for fluorescence diving and it's a working perfect. I will order more leds to build more of these lights, top product.

    Pros: bright, works nicely, amazing value Cons: it's only 10 pieces, so it didn't came with a box. try to search for another LEDs on dx.com, that comes with free box. Works nicely, great for DIY projects, illuminate blue beautifully. great value, great item overall

    Brightness & Price... All package fully operational. Used them for decoration with 2 AAA batteries (3Volts).. Even had to use 120ohm resistor for each led on some projects to reduce brightness in pitch black ambient light. Very low power consumption. None that I can remember. Although there... Read more

These leds runs best at 3,3v. I measured brightness with that voltage and it was 3840Lux @ 10 cm. I tried but... Read more

    These really glow bright blue!. I have been using these in guitar pedal projects for a while now and have not had any failures. They seem to be well constructed. The 5mm size is a handy size to keep available at my work bench. They have a very clear lens. They also have strong metal leads which a... Read more

    Very cheap and insanely bright. I can use them for building my own growing light. It's cheaper than buying LED lights from local electronic store. Shipping time approximately 3-4 weeks, not a big deal because I only have spare time on weekends. Now I'm building LED matrix using these LEDs and is... Read more
