水草情迷

好光喎...
想問有無分k數?

where can i buy this part?

vkcy:
I bought it from "bunnings warehouse" in Gardening section. I'm not sure where you can buy it in Hong Kong.

keisuke:
To be honest I don't know what the colour temperture is. they have warm white and cool white plus other different colours to choose. mine is cool white. as I know LED has very narrow spectrum. I was taking a risk to use LED light and I didn't know if they are suitable for aquatic plant growing. Luckily my plants growing quite well so far.

compare LED to fluorescent tube in lumen/watt, LED has slightly lower efficiency than f.tube. but LED consumes less power and produces less heat.

ctchung兄

謝謝提供資料！呢隻LED個款有ｄ似依家車用既低燈，但我唔敢肯定是否同一款。

請問可否再提供多些資料，如魚缸水溫度？因為你講LED背面係較熱，差不多有成40度，而且見你既蓋係全封缸頂。

另有火牛spec，LED driver等資料？謝！

the lighting system is really amazing...
nice diy, i like it very much.
but is there any substitute for the led u used?
