I have purchased this UV lamp for two purposes. The main reason was because as a stamp collector I needed a high-quality dual wavelength UV lamp to detect both fluorescence and phosphorescence of stamps. The UV lamps I have used for this purpose in the past did not really meet my expectations. In contrast, the BioGlow UV lamp is absolutely great for this purpose. Using this lamp, I get very bright fluorescence and phosphorescence signals I can easily take clear, high-quality photos of (something that was quite often was a big problem before I purchased the BioGlow lamp). So, I can highly recommend this handheld UV lamp to any stamp collector to detect fluorescence or phosphorescence of stamp paper.
By the way, this UV lamp is also perfect for checking fake banknotes or banknote collectors.
The second reason is work-related. As a molecular biologist, I work with DNA that needs to be run on gels and/or gel-purified. The handheld UV lamp allows me to check DNA on the gel without removing it from the gel apparatus and transferring it to a transilluminator, thus saving time and gloves.
As the UV light is quite intense, I always make sure to wear UVEX safety googles when I use the lamp.
The UV lamp is very easy to use, light, and the cord is long enough to easily operate the UV lamp. I am very happy with the purchase. I just wish I had known about it much earlier.
