Class I - Dangerous
These 500-watt light bulbs generate very high temperatures, compared to incandescent and lower wattage halogen bulbs and can start a fire, if they come in contact with curtains, clothes or other flammable material. These bulbs are intended for use in outdoor work lights and flood lamps. To meet the current Underwriters Laboratories standard, halogen torchiere floor lamps must be equipped with a protective glass or wire guard and have a halogen bulb that is 300 watts or less.
