Tutorial - Energy Efficient Fluorescent Lighting
about 6 years ago
It is great to see you all are sharing ways to both save money and reduce energy usage. I have been doing this at my home (on a much smaller scale) and wanted to add that not only do you save energy but the bulbs are lasting longer, they are noticeably brighter, they run at a much higher frequency so there is no flicker and amount of heat produced is much lower.
However, not all electronic ballasts are created equal and some of actually worst the ones they replace. You did not mention the specific ballast you were using but I have used the Fulham Ballasts and so far these have been working great but wanted to know which ones you are using?

The Saleae Logic is my new favorite tool! The ability to analyze serial communications has save me 100s of hours of debugging - it completely blows away trying to debug using other approaches, including using a scope.
It is also great for debugging logic timing issues and signaling problems. The ability to see when the logic states are really changing and to be able to measure the timing between them makes simple work of finding tough problems.
The design of the tool and the included software is exceptional. I have yet to find any serious bugs - very impressive for a new product - and it is fun to use.
Another feature I really appreciate is the wires are extremely flexible making it easy to connect them while you are breadbording or to PC board ? they do not ?pull? like the wires from many other tools do.
I highly recommend this product!
