I've been using the mercury vapor bulbs for about a year now. The one thing that you must do with mercury vapors is make sure they are pointing down (not at an angle). As long as there's correct wattage and has the ceramic ficture and the bulb fits the lamp, you could use. However, this lamp looks to be designed mainly so you can use at an angle. Also, I've noticed that many of the mercury vapor bulbs are larger in size & only fit nicely in the deep dome lamps. As long as the lamp can hold the bulb, allow you to sit it vertically, has ceramic socket, and has correct wattage, then you can use. This lamp seems to not designed to use with those but does look great for other types of lights. I hope this info was helpful.
