Rated 4 out of 5 by sideprongled Only Bulb Available
I have track lighting that requires a compact par38 bulb with a medium side prong base. These are in groups of 4 on 600 watt dimmers, with the original bulbs all being 150 watts. It took a while to find these bulbs, since the main market is for mineshaft lighting. (Compact MSP bulbs are much shorter than other PAR bulbs.) Apparently GE is the only company still making these bulbs for bulk sale in the US market, because I could find no other bulb of this specification for anywhere close to this price.
That said, I would LOVE to be able to convert these lights from Halogen to high CRI LEDs like the Sylvania Ultra HD series - even if I had to give up some lumens. But obviously there are no LED bulbs with medium side prong bases, so I didn't have a choice. I am sure I will convert them eventually.
It is also worth noting that the GE bulbs were not quite a bright as the bulbs they replaced. Maybe they need to burn in before they reach maximum brightness..
