Hello....

Threre's a place i have read that the led lasted 100,000 hours, if i'm not mistaken... last time at lelong it sold at RM8.00 for 10 leds.... i heard that led is more power efficient than normal lights.... i'm trying to use 8 led for my 1.5' tank that filled with riccia.... dunno it is going to pearl o not.... plus led produce less heat....
