I bought the LEDs in green, red and cool white for lighting a screen. They are super small but really really nice shine intensely. From the color intensity they are but different. (E) by far the Green Chain burns brightest. White also makes a decent light, however, the red is a bit poor, which chain is the only well that instead comes with 2 AA batteries with 3 out. Why this is so, I do not know, but I would have done it differently. Unfortunately, the Green Chain held but not long, because it is my broken after a short time (and the stress was really not great) and the lights number was reduced from 20 to 13 spontaneously. Since then I have a little afraid to touch the other chains. Apparently you can solder the back if you can solder because I definitely can not and therefore they simply wander with me in the garbage. But otherwise beautiful lights. Since I still bought in addition to these a hundred micro LED chain from another provider and was also very good (and probably comes from the same production company probably eh everything) you need a bit of luck apparently what you now caught for.
