I just got off the phone with PIAA tech. He confirmed what I believed and pointed it out in their glossary:
"XTRA
A PIAA term used to designate high efficiency bulbs that are designed to produce greater light output than its rated power consumption. (Example 55watts = 85watts of light output"
He further stated that the bulbs will draw the same amount of wattage but put out more light (measured in watts, ie 55 = 85 watts) . He further stated alot of bikes, should you put in a 100 watt bulb in a housing designed for a smaller wattage bulb, melting from extra heat is a distinct possibility..
In either case, I have to agree to disagree. These PIAA's put out more light than the stockers, I can see that. Its not going to be as bright as a halogen modified set up however I DO NOT want to hack up the headlight assembly, heat light assemblies to take apart, etc. The light output of what I have is plenty for my needs...
As for the new (110 volt) florencent light bulbs drawing say 27 watts and putting out approx 100 watts of light, I have several of them thru out the house and they indeed put out the same amount of light of an incandecent 100 watts bulb...
Yes what they are saying is correct. And I'm sure they put out more light. They just don't express it in lumens and watts don't equal lumens.
