STAGE SPOTLIGHTS - THEATRE STYLE
Hi Tech Stage type spotlighting
The stage spotlight look is currently a very popular theme in shops and businesses quite aside from its uses in the theatre. In reality except perhaps for amateur dramatic use these are much more readily found outside than inside a theatre.
The basic SFL PAR20 GU10 Spotlight uses a conventional GU10 mains power 50 watt halogen or LED lamp and so is more suited to domestic or perhaps small shop use.
The SFL PAR36 ES111 uses a halogen lamp which is more than twice the diameter of the PAR20 and therefore gives considerably more light ouput than its smaller brother.
The SFL 70 and 150 watt T and TS spotlights are very much more powerful and efficient and give a quantum leap of light output when compared to the cheaper halogen SFL's. The choice of T or TS is simply the Metal Halide lamp used. The "T" version uses the common G12 lamp format and the "TS" the Rx7s the linear equivalent.
There really is very little difference between these versions apart from 70 or 150w power - if your store is already using one or other of these lamps then it makes sense to choose the one you normally use.
