This cost me about NT 150 dollars (roughly 6.x USD).
And the plants in this tank bubbled.
Here's the list:
1. A philips tornado ---- 115 NTD
2. A drinking water bucket ----- free
3. An E27 bulb's stand ------- I got this from an old OA lighting,it costs 15 NTD in Taiwan.
4. Silver cutting sheet-------25 NTD
the bucket's mouth is perfectly suited for the e27 stand so I didn't use any tool to screw or glue it.
Just insert the stand and install the bulb so it would be fixed.
Paste the silver cutting sheet on the cutted water bucket so it would be the reflector.
I do think this light is not so good, be it works for me for a time being.
