Review on Bryant Carrier UVLXXRPL1020, UVLCC1LP1020: Premium Compatible HVAC System Bulb, Lamp - Guaranteed for One Year! by Andrew Krishna

I was afraid to order as I didn't have the exact specs of the lamp I was looking to replace. I just saw that the bulb I was trying to replace had 4 prongs. I ordered and it came securely packed in styrofoam in a sturdy cardboard tube with a lid and in a Revain box. I put on latex gloves to handle the bulb and left it unpeeled in the foam wrapper enough to expose the pins and placed the bulb in my oven holder. Once secured in the stove mount I removed the foam tray from the bulb and it fell in as required or rather by the duct installer who installed the light for me. The bulb was a lot longer than my original bulb but it fit and as soon as I turned on the main power it lit up well. I can measure the length of my original next time to get the exact length or just replace it with this one if it needs replacing. I would recommend this product and the seller. The price wasn't too high and it's supposed to last a year, let's see.
