### ⭐⭐⭐⭐⭐ It's Great
*by M***D on March 5, 2020*

My wife uses it in her daylight magnifying light for cross stitching. It was a replacement for the blub that burned out, had it for decades. She says it is brighter

### ⭐⭐⭐⭐⭐ fits naturalight magnifier desk lamps
*by D***H on October 5, 2019*

searched high and low for this bulb, ordered it not knowing if it would fit my lamp (naturalight) but it does, works so well I ordered a second one for a spare

### ⭐⭐⭐⭐ Worked in Naturalight UN1030
*by F***M on December 30, 2019*

UPDATE Aug 2022: Bulb worked great for about 2 years. This is substantially less time than the original. It has been flickering for about 6 months. Can't tell if it's the bulb or power supply. Original Review Dec 2019: Worked as direct replacement for my Naturalight UN1030 magnifying lamp. This bulb is hard to find. Without direct physical comparison it is difficult to know if it would fit. At first it worked for about 2 seconds. Then I discovered the switch was also bad. I bypassed the switch and it works fine. Now to get a replacement switch.....
