Adding Glass Shields to HPS reflectors
1. First of all, you'll need a
Reflector with HPS of course I think that way of adding
glass will be suitable for many kind of reflectors.
[Eco Green's note:Venus has used a batwing, but this
technique can be used on many different shapes of
reflectors, as long as there is adequate clearance
between the bulb and glass. Large 1000w MH bulbs may not
fit inside glass-enclosed reflectors]
2. That is
all u need:Pliers, Sidecutter, "Philips" screwdriver,
5mm bit for making holes in reflector, 4 bolts, 4 "L"
shaped brackets, a ruler, electric drill and isolating
band (rubber/elastic tape). Note the bolts and "L" shaped
brackets that I used.
3. Now, to
make this done u will need a peace of glass. Take the
ruler and measure the size of glass u will need. Hardware
stores, windows shops, etc will cut any type of glass you
want. Bring your measurements. I used regular, 1/8 (3 mm)
window glass. Here is the peace they cut for me using
sizes I gave them.
[Eco Green's note:most window/glass stores can make
fabricate/cut tempered glass (high heat resistance, thin
and light, but high cost), or regular plate glass
(lower cost).
Tempered glass is preferrable for high wattage lamps, as
their heat is extreme. Plate glass can crack under these
hot properties.]
4. Take the
electric drill and drill 4 holes in each corner of the
reflector. To make this, I used a 5mm bit.
5. Take the
isolating band and cut it with scissors in half......I
doing this because the width of the iso-band is more
wider than the "L" shaped bracket. Now ,take that half
cut iso-band and just roll over the "L" shaped bracket.
That way, the glass will sit on a soft surface instead of
a metal surface - protecting it against scratches,
vibrations and slip over...
6. Take the
bolts and brackets and screw them all together to the
reflector......
Then, flip over the reflector and slide the peace of
glass into it.
Here u can see how it will look with the glass sitting on
the brackets and just below the bulb......I kept 1.5 inch
(4 cm) between the glass and bulb.
7. After all
dirty work is done, the final product looks gorgeous and
will do the job it was intended to do......
With all stuff prepared before doing the job ,yuo can
finish all this in about an hour ....
