Review on 🔆 Simpo Horizontal Retrofit Replacement 3000 3500K: Advanced Lighting Solution for Vast Horizontal Spaces by Joshua Sarma

These bulbs fit very loosely compared to my 7w PL-S fluorescent bulbs. You have to wiggle them in the plug to make them light up and work, and just hope they stay. I just measured the square plastic base on both lamps that fit in the socket. The new replacement LED bulb is 0.51" wide and 0.50" deep. The old original fluorescent base is 0.525" wide and 0.62" deep. No wonder they hang out at my outlet. Bad quality control. I'll keep going and see if they work.
