Philips created an ad campaign to air on national television revolving around their Halogen bulb collection. In the process of this, they created a "retail shelf" line called Halogena'. If you look at regular halogen light bulbs from Philips and their halogena' equivalent, you will find that the specs are exactly the same. So, it really doesn't matter whether the name Halogena' is on the box. If it's from Philips, it's a quality product.
