An electrical device, e.g. an electric lightbulb has various electrical and/or optical parts contained inside an envelope, and is made by attaching the various parts to selected fingers of a metal mount which is stiffened by transverse braces interconnecting the fingers, the mount being inserted into and sealed in the envelope so that the braces are inside, and the braces subsequently being breached by the intense heat generated by a beam of laser radiation focussed thereon. |
