Most lamp holders will not catch fire but may decompose and become brittle with excessive heat. A T2 lamp holder is rated at 100 Watts tungsten maximum I believe. I think that T1 rated lamp holders were rated at 60 Watts for tungsten bulbs. As suggested why not fit a new L.E.D. light bulb which is very bright and low Wattage. A warm white colour output will be close to the old filament bulb's colour. New L.E.D. bulbs can be bought in shapes that resemble the old hot running filament bulbs so do not look too out of place. It will have something like 3000K printed on the box for a warm white colour output quality.  The lumen output is a guide to brightness. The higher the lumen number the brighter the light output. New L.E.D. bulbs often have an equivalent value  printed on the box, e.g. 10 Watts real power relates to an old 70 Watt light bulb as a rough example, even though 70 tungsten bulbs were not made. It is just a guide.
