Osram Halolux Classic A60

The original halogen retrofits for European GLS lamps consisted of a double ended quartz burner sealed within a BT shaped outer envelope - similar to the Philips Halogèna range. These were marketed as premium products intended to up-sell the consumer to the higher output, whiter light and longer life offered by halogen technology. While the different bulb shape was effective in distinguishing these lamps from GLS products and delineating them as a higher value product category, it also proved a weakness in that many consumers did not make the connection that they were suitable as an alternative to GLS in all applications.

A simple change of format was introduced in 2004 with Osram's Halolux Classic illustrated here. Osram made the important move to switch to the ordinary pear shaped glass bulb as used on GLS products - thus making the product appear to the consumer more like the familiar incandescent products. Backed up by a strong marketing programme at the point of sale in retail outlets, Osram was much more successful in the marketing of this product than had been the case for previous versions with the fancy BT bulb shape.

Technologically the Osram lamps are different from their predecessors because they mark the first use of a single ended mains volt capsule inside an outer envelope. In fact the source employed is based on the company's G9 Halopin capsule. This employs the bulb-pinch method to support the filament at three intermediate points and features the same integrated fusing technique as for G9. Secondary fuses are also provided within the stem of the outer bulb. A third heavy lead wire in the stem is attached to the capsule via a metal strap to provide the necessary mechanical support.
