owned since new and my bulbs go in 6 to 9 months, and usually in pairs. I've had both sides go out within hours of one another and always have spares with me. I've gone to cheap ebay bulbs since it didn't matter how much I've spent. Touching bulbs not an issue if you use nitrile gloves.
Well different materials/substances do conduct heat differently but I just can't see how a little grease/oil could cause such a drastic increase (or decrease) in heat transfer. I mean, nothing is rubbing or blowing over the bulb so surface roughness or finish don't have any impact. Sounds like a myth to me.oils and grease causing hot spots?
or is that a myth?
