What does "blue" mean?** A: typically, the white light seen from an incandescent bulb is in the yellow part of the light spectrum. some incandescents are designed to provide light in the blue portion of the spectrum, e.g., white light. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Mag lite replacement bulbs *by K***G on June 29, 2026* I have purchased these before and they work well and last long.
