Review on NICREW Submersible RGB Aquarium LED Light Stick - Underwater Fish Tank Multicolor LED Lights with Remote Control - 7 Inches, 2.5W by Brenda Ward

Update September 11, 2020: They are still on sale. No change since I last received it. Works very well. It's really good for this price. I see one at Walmart and it doesn't even have those color change options etc and it's about $20. As you can already see from the description, there are many lighting options. You can even lower the brightness (only works for one color, doesn't work if you use the change light options). The cable is long enough, I hang it on the wall so the sensor is at the back but still visible. I hope the lifespan of these bulbs is not too short, but I will report if they fail too quickly.
