Next to the Ecosmart lamps, they sell a Philips lamp, 19.5 watts, comparable to a 120 watt halogen. The Ecosmart lamp has more of a flood spread to the beam. Ecosmart work, but I like the Philip spot/color better, I tried both. The Philips has more of a spot. I've been using the Philips lamps for a few months. I added more spot to my gigs, and they have responded very very well to them. Most reefers don't like white lights (I do), most like over saturated blue. The Philips are dim-able. I never tried it with a mag, but for sure, all my gigs like them.
