Philips Infraphil HP3614 heat lamp
1993 word mark of Philips Infraphil HP3614 heat lamp packaging (top) and armature (bottom)
THE-1990s-INFRAPHIL-WORD-MARK
Around 1990 the red italic font for the
packaging was replaced by a non-italic
font and again a new Infraphil word mark
for the armature was introduced. It is this
logo that was present on the last Philips
heat lamps to be sold under the brand
name Infraphil until the end of 2009.
