Over the years, I've learned that most things sold and marketed by reptile supply companies can be purchased MUCH cheaper if you know where to shop. But, I don't want to take a chance when it comes to the UV lighting. I know that Mercury Vapor bulbs have been around for quite some time, and you can buy them for a fraction of the cost. Does anyone know what specs to look for? I'd rather spend $15-$20 than $60! Lol.
