I have 3 units of twin tube T8, 48". Each unit cost me about $20, including the bulb. Each bulb has 32w rating.
I have 6500k daylight deluxe, which is on the BLUE side. From what I have gathered the blue spectrum is good for seedling growth where you don't want flowering and fruiting.
This is the second season I am using them. They are compact and at the end of season I just pack them into the original box.
It works great for my needs. I grow about 30 peppers and about 30 tomatoes.
