The extra heat generated by the brighter bulb would be a major issue, especially in an enclosed space under a colored reflector filter or inside a smaller outer dome, even though Code 3 commonly used them in the fast rotator under an MX7000 center dome. Plus, any reflector's surface would either flake or tarnish faster if it is metal or melt completely if it is plastic.
Pete L. said:+1 on what 03crownvic said. You may want to check your rotator reflectors.
The StreetHawk came with both alum. and plastic reflectors. If they're
dull, that will effect the flash.
Richard P said:The streethawk is already the brightest halogen bar to date, especially with the h155 watt bulbs, you shouldnt have a problem. does yours have the 795 bulbs or the h1? maybe you have a bad ground causing it to be dim? it has the largest focused parabolic reflectors aside from the old target tech bars.
the 795 is a 50 watt halogen, the h1 is 55. Unless you use a large mercury vapor streelight bulb, you already have the brightest
