The technical data are already correct, in practice schauts different! A PAR38 100 Watt lamp can therefore not be replaced. The light color is not unpleasant, but it goes a bit into Pink. By 90 ° beam angle, the lamp of the radiation pattern looks like a light bulb. The term SPOT she leads entirely wrongly! It is called with PAR38 lamps with 36 ° beam angle of already FLOOD lamps. Lamps of this type are intended mostly used for object illumination. For this task, it is really useless. It goes back, therefore. The relatively good rating is because the price is right and I have tested even expensive lamps that were not at all to use
