THIS DUAL HEAT LAMP IS CONSTRUCTED OF HEAVY DUTY ALUMINUM, SO IT'S LIGHT WEIGHT AND EASY TO TRANSPORT ON- OR OFF-SITE. THE ARM ADJUSTS EASILY FROM 15 INCHES TO 21 INCHES HIGH, SO YOU CAN USE THE LAMP TO KEEP A VARIETY OF FOODS AND DISHES WARM UNTIL YOUR GUESTS ARE READY TO EAT. THE FLARED SHADES RESULT IN EVEN HEAT DISTRIBUTION, AND THE ON/OFF SWITCH IS CONVENIENTLY LOCATED ON THE ARM AWAY FROM THE HEAT ZONE. THE LAMP COMES COMPLETE WITH 2 CLEAR BULBS, 250W EACH.
