You need to buy a spiral cfl with the proper wattage you want.
Build your own fluorescent light fixture.
Now for building your own fixture.
Just attach the bulb ballasts plug it in.
This greatly decreases the cost of the fixture.
A fluorescent tube that is failed or failing usually has darkened areas near one or both ends of the tube.
I want to build several letters out of fluorescent light bulbs for example one letter is o but it will look more like.
From scratch without buying light fixtures and taking them apart.
Each letter will be constructed of 4 lights.
To replace remove the old tube and bring it to the hardware store.
Locate a ballast as i mentioned above i have been recently experimenting with using spiral cfl ballasts to power other bulbs.
Or you can read the printing on the tube to identify the correct replacement type.
For t5 s and pc bulbs the wattages are basically equivalent.
I want to use bulbs that are 2 4 feet long or what ever is easiest.
Build a customized fluorescent lamp system t5 when growing seedlings and plants in the vegetative stage using fluorescents is a great way to provide the beloved plants with bright and balanced light.
