SY 1 x
40w fluorescent lantern. Made
by ST Lighting of Thailand this exterior fluorescent
lantern is widely used in Thailand for commercial and
domestic use. This model uses a single 4ft 36w/40w T8
tube with glow starter. A double tubed variant is also
available for twin (side by side) 4ft 36w/40w tubes,
and there is a smaller 2ft x 20w variant too. These
lanterns tend to be used for lighting minor roads, access
roads, and driveways to commercial premises.
After finding one of these
lanterns for sale in a electrical shop in Patong, and
despite the length of the fitting, I decided to take
the risk and buy one to bring back to the UK with me.
The lanterns don't cost a lot, mine cost 500Baht
(about £8.00p), but they come without a ballast, starter,
or lamp. However, these items are very cheap to
buy and are readily available, so I bought the ballast
and starter separately, but didn't bother buying a tube
as it would only get smashed in transit. I could have
had the bracket and mounting plate for the lantern for
another 250Baht (£4.00p), but decided that I'd have
enough problems in getting the lantern back to the UK
as a standalone item.
I knew the lantern would get
thrown in and out of the holds of two aircraft along
with all the other baggage, and there's the luggage
carousels at the airports to encounter as well, so I
thought it best if I packaged the lantern myself.
I persuaded the girl in the shop to let me have some
cardboard, newspaper, and packing tape, and I set
to work packing the lantern up. I packed the lantern's
bowl out with newspaper to try and prevent the bowl
getting crushed during transit. I wasn't sure that this
had worked in protecting the lantern until I was able
to open the packaging on my return to the UK; happily
the lantern and the bowl survived OK.
The Nulite 36w/40w ballast
was not supplied with the lantern and had to be bought
separately for 65Baht (about £1.00p), but a set of fixing
screws and nuts are supplied with the lantern, and the receptacle holes
are already pressed out in the lantern's gear tray/reflector
panel to fit the ballast against.
The
fitting has a cast-aluminium canopy and an injection
moulded plastic bowl, but no refractor surfaces
are moulded or bonded into the bowl. The general quality
of the canopy's casting is very poor, and additional
filling with epoxy resin has been carried out on the
canopy by the manufacturers to fill the blow-holes in
the casting.
Here's the SSLL 'SY'
lantern complete and assembled prior to testing.
The mobile phone has been placed alongside to
give a sense of scale.
After wiring the lantern up
to a feed supply and fitting the tube, the power was
switched on and the lamp ran up perfectly first time. The
brown mark showing up on the rear of the bowl is the
remains of cardboard from the original box has got stuck
to the bowl.
