About the LS 135 Examination Light
The LS 135 examination light is a 35-watt halogen light that produces significantly whiter, brighter light than the ordinary gooseneck units. The dual intensity control switch allows you to instantly adjust light output to meet your exact requirements. A molded lexan light head does not conduct heat, keeping the luminaire cool to the touch. Multiple installation options include floor stand, table mount, wall mount and caster base.
About the LS 150 Examination Light
The LS 150 features a color corrected 50 watt lamp that delivers superior light quality across the variable spectrum for more accurate color rendition. The special designed light head keeps the luminaire cool to the touch even during multiple exams. The lamp has been offset at a 12 degree angle relative to the luminaire housing, allowing an unobstructed view of the field of interest.
