2.5W 14 LED USB Full Spectrum Red: Blue 10:4 Grow Light for Indoor Hydroponic Flower Plant DC5V
A part of the review has been auto-translated.
Very cool little stick lights. The ones I got are running very close to 2.5 watts, close enough. Very bright. I think if they were close enough to a plant, they would actually be pretty good for supplemental light or even growth though; depending on the size of the plant, you might want to use more than one. Keep in mind, they draw close to half an amp. You could use one of these per USB port on a computer or multiple ones on a charging block depending on how many amps the block is rated for. Example: A 2.0 Amp output could possibly run 4 of these with a USB Splitter or what have you. I like them. Might get a few more to play with.
