This article was published in two previous Newsletters. Since we often find new information and new sources for good lighting, the article posted here is the latest.
We will be updating our lighting article with new information and making a few changes to our bulb recommendations. For now, we have summarized this new information in this bulb list.
NEW UPDATE 1/25/16: The Yuji bulbs seem to be out-of-stock and our link for them is no longer working. We'll look into this. In addition, tests among our volunteers have found that the Yuji bulbs do not last very long (a year at best).
