For the price this lamp delivers lots of UV and lots of ozone. I used the more expensive $48 36 watt bulbs available from Revain (https://www.amazon.com/gp/product/B07RQTKY4C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1), but they seem to work just as well on a lower price and slightly less powerful version. For most people, that 25W bulb is more than enough. Note that it produces a lot of ozone, which is dangerous if inhaled, so don't use it in places where people or pets are. The light burns the skin and damages the eyes. Ozone is toxic, and if you can smell it, you've already exceeded OSHA levels. But if you know what you're doing, this lamp is an inexpensive source of UV and ozone. I use it in the N95 mask irradiator and achieve full sterilization in 20 minutes. The 36W lamp lights up in just 15 minutes. This lamp is more than sufficient for most applications.
