Osram's Dulux EL
range are without doubt one of the best known work horses of the CFL
world. While nothing groundbreaking, they're reliable good
performing lamps. The conventional form factor meaning that they
seem to be losing a bit of ground domestic market these days (purely
based on my observation of how readily available they are locally!) as
spiral designs are becoming more popular as they don't fit into many
traditional lamp shades. The long (and consistent) lives mean
that they're likely to remain a staple of businesses for quite a long
time I imagine - the fact that they've been around for ages will help
there too.
PAR36 lamps have been around for a long number of years, and still have
quite a following for floodlighting purposes. These lamps however
are very expensive, even when bought in bulk - so any physically
compatible lamp which lasts some 10 times as long is obviously very
attractive! In response to this, Osram seem to have done
something very simple but very effective - sticking a big stippled
reflector to their existing 15W and 20W Dulux EL CFLs. This
results in a lamp which gives a nice even flood of light, while
producing far less heat than the equivalent PAR lamp, and with a far
longer rated lifetime.
There are a couple of ways in which this falls short of the PAR36 lamps
its intended to replace however. Not least in that it isn't
suitable for dimming - many PAR36 lamps in places like hotels and
restaurants are coupled with dimmers - so these lamps can't be used as
a direct replacement there. Also, PAR36 lamps are by virtue of
their original intended outdoor application, weatherproof, so with the
appropriate type of lamp holder can be used outside, hence quite a
number of older security light systems using them. This lamp
would require a fully enclosed fixture if it was to be used outdoors.
Very typical Osram product - in that it does what it's designed to in a
very direct, efficient way. No time or resources are wasted in
looking fancy or incorporating features that nobody will ever need.
