I do like their low power consumption but to have a whole board covering the tank due to their concentrated focus seems a hard call. Perhaps it may be possible if (a) Someone comes out with a 6500-8000k LED bulb (b) Someone designs one that is aethesitcally pleasing. Cheers, Jerome |

... I had one set which I DIY a year ago... Using super bright leds,blue. I know what's the effect like.
1. Brightness does not mean good PAR and penetrating power, pretty weak actually. It appear bright because you are looking at the light directly. If you look at MH , you'll be temporary blinded.... 2. The article link showcase only a 3 gallon tank using 32 LEDs. Cost wise.... more than 100+ dollars. E.g to light up my 2 feet tank , I would need about 200 odd LEDs packed together to be comparable to a 36 watts PL/FL, perhaps 350+ LEDs to be a 70 watt MH.... 3. Water penetration is weak, not recommended for tanks with 2 feet+ depth. Definitely not recommended for planted setup, even for "low-maintainence" system. At most you use it as a "moon light" setup. Conclusion 1. Expensive 2. Cute to have, moonlight 3. very limited use in a planted tank Last edited by plantmania; 03-03-2005 at 03:34 AM. |

By the way, there are "white" super bright LEDs, that are around the range of 8000K to 10000K. Of cos you need hundreds of them to work as a planted tank light source, which also means freaking expensive for anyone to swallow.
For me ,last known price of a super bright LED is 4 dollar a piece , that's consider on the cheap side.... There's also the normal LED, cheaper around 1 to 2 dollar, not recommended though, is extremely weak. Site recommended 680 LEDs for a 4'x 1' x 1' marine tank....Price estimate = 700(round up) x 4 + 100(power adapter,circuit boards and some waterproof shielding) = 2900 SGD. Okay "let assume" price drop 20% per annum. That means it will take at most 11 years before it reach affordable price of around 250 dollars.... Last edited by plantmania; 03-03-2005 at 03:42 AM. |
