A portable electric lamp of explosion-proof construction including an elongated hand grip, an elongated flourescent bulb having a U-shaped light-generating portion supported at one end of the hand grip and a transparent tube positioned about the light-generating portion of the bulb utilizes an elongated tubular protector element positioned about the transparent tube and which cooperates with the hand grip to maintain the transparent tube in position about the light-generating portion of the bulb. The lamp further includes a power cord routed through the end of the hand grip opposite the light-generating portion and the lamp includes an amount of magnesite base cement positioned in the hand grip and interposed between the light-generating portion and a section of the power cord entering the hand grip. The lamp further includes a ballast assembly having a ballast interconnected in the power cord at a location remote of the hand grip and wherein the ballast is encased in magnesite base cement. |
