considering $50 to change 10 000 LEDs from blue to white, it's a very good offer.
It means each LED cost a mere $0.005. Compared to present LED's price, US$1+ for a good blue one and US$2 for a good white one. The money you saved is few hundred times. With so many you can coat with it, i don;t think people will want to buy so many bottles and getting rich from selling the lotion is unlikely. |
