Say we refer to candle power or wattage of a light source. Is candle power recorded by the object relative to the velocity of that object ? In other words does the light get brighter the faster you are moving towards it? [ even after you take length contraction in to account.] According to relativity and also any experinments done. Is the brightness of light only determined by distance from the source? Can Special Relativity Theory accomodate this issue? Just find this aspect facinating and look forward to some informed responses if possible...
