I believe all bulbs give off a very small amount of UV light, but nothing that would harm your lamp. If anythng, a frosted bulb may give your lamp a softer light than the clear bulb. I use 100 watt frosted bulbs in my Grandes and 25-40 watt clear bulbs in my 32 oz. and 52 oz.
Ah, thanks. I just changed out the clear 40 watt bulb in my Enchantress Planter for a frosted one and it doesn't look as good as the clear one does with the colors. I did this in fear that the clear one would fade the globe. But if that is not a concern I will change it back. I do drape T-shirts over them during the day when the blinds are open to protect them from the sun.
