I have a pair of identical YDD Lightsabers that I bought on Amazon a few months ago - one green, one blue. I had the idea to use lightsabers for my up-coming gender reveal, because I'm a huge nerd and everyone knows it. I didn't want to spend $89 for another lightsaber in a different color, so I took the green one apart and got a look at what the LED was like - it looked identical to these ones here! I has a focusing lens on top of the LED, and the LED is soldered to a star-shaped board (which I also ordered), and there is a heat sink attached to the bottom of the star-shaped board. I re-purposed the focusing lens and the heat sink, and soldered one of the new Chanzon pink LED's onto one of the star-shaped boards that I bought for it, and then the wires to the lightsaber's control board and put it all back together. Even though the LED is 3W instead of the 5W green LED that was in it, it's nice and bright! This photo doesn't really do it justice, as the color is washed out and uneven through a camera lens, but isn't at all in person - it's a very bright, even color! Very happy with these LED's!

LED aluminum substrate is used, because aluminum has high thermal conductivity and good heat dissipation, which can effectively dissipate the internal heat. Aluminum substrate is a unique metal-based copper clad laminate with good thermal conductivity, electrical insulation properties and mechanical processing properties.See more Posts >Hyuduo

LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a support, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. LED features advantage: The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses. small volume LED is basically a small chip encapsulated in epoxy resin, so it is very small and very light. Low power consumption LED power consumption is very low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. This means: it consumes no more than 0.1W of electricity. long lasting Under the right current and voltage, the life of the LED can reach 100,000 hours High brightness, low heat Environmental friendly LEDs are made of non-toxic materials, unlike fluorescent lamps that cause mercury pollution, and LEDs can also be recycled. strong and sturdy LED is completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There is no loose part in the lamp body, these characteristics make the LED can be said to be not easy to damage. Effect The biggest advantage of LED lights is energy saving and environmental protection. The luminous efficiency of light reaches more than 100 lumens/watt, while ordinary incandescent lamps can only reach 40 lumens/watt, and energy-saving lamps are hovering around 70 lumens/watt. Therefore, with the same wattage, the effect of LED lamps will be much brighter than incandescent lamps and energy-saving lamps. The brightness of a 1 watt LED lamp is equivalent to an energy-saving lamp of about 2 watts. A 5 watt LED lamp consumes 5 degrees of electricity in 1000 hours, and the life of the LED lamp can reach 50,000 hours, and the LED lamp has no radiation.See more Posts >Othmro

Very Bright
I was impressed that the parts were shipped in a sealed anti-static bag. Most of the parts I've bought from various sellers, except Jameco, usually come in a plain plastic bag which doesn't really inspire confidence in their reliability. I haven't had a problem (yet) but the parts are cheap enough. That said I unpacked the LEDs to test them (this is routine for me) and found that they are indeed extremely bright when driven with a 3v power source. A word of caution: these LEDs radiate up to 380 nm in the UVA spectrum (320 to 400 nm) so don't view them directly. The UV curing lights radiate at 410 nm so I guess you could cure UV glue with these devices. I haven't tried it yet but I probably will just for giggles and grins. They will activate fluorescent paint. Anyway I am pleased to say that I will be buying from this seller in the future.Update Mar 2019: I put together my grow light last year with the COB LEDs mounted to a fiberglass protoboard. It worked well last season; however, the system failed on me this year. I screwed up by not using the heat sink mounts for the LEDs. 3 watts may not seem a lot but concentrated in a small space the heat built up charred the board and the LEDs failed. My bad. My new design uses the star type mounting plates for the LEDs which I cemented to the aluminum plate with ArcticAluminum thermal epoxy. Now the devices run around 24C way below their rating.

But they're rated 500mA which they get at almost 2V which is exactly 1W.
So also they're little bit expensive for 1W
Other than that they do what they should do.
