I'm putting all my lights on timers and discovering some aren't self-starting--you need to push and hold a button to start. Is is easy/cheap or hard/expensive to change them to self-starting? Has anybody done this? Is it cost effective vs. buying new light? What if I wanted to add a second bulb for plants? Do you put new 2 bulb fixtures in the old plastic box or do you buy all new fixtures?

I'm not very skilled with a soldiering iron, but I do own one and I have replaced non-polarized cords with polarized ones.
