Review on 💡 GE Lighting 33890: High-Performance Fluorescent Lighting Solution with Optimal Diameter by Tasha Folan

If, like me, you pay attention to the K-rating to ensure your light is always the same color, you might be disappointed . They are warmer than I expected. GE advertises them as 4100K, but I'd say they're in the 3000 range. I'd put them in the same boat as "fluorescent lights" which are a bit warmer. These are definitely not clean (blue) bulbs. The lamps work well, are easy to install and don't flicker which is why I give them 4 stars.
