If you are
interested in growing
vegetation, we hope that we can help
you out. This lamp puts out light in the
critical blue
region needed for strong stalks and chutes.
It should make sense that plant receiving
plenty of diffuse light from the blue sky
doesn’t need to grow taller. Instead they
should concentrate on bushing out.
This auction is for a new
400 watt conversion bulb. It will make more
natural white light on your existing
orange light ,
HPS (High
Pressure Sodium) fixture.
Don’t
get burned with the so called
switchable grow lights. Normal metal halide
bulbs and HPS bulbs operate on different
voltages (310 volts & 215 volts). Switching
an igniter in and out will either fry
electrodes and prematurely burn out ballast
coils with one lamp, or seriously under
drive one of the lamps. This underpowered
lamp dims and loses efficiency. (Light
output drops faster than wattage reduction.)
‘ used to sell a lot of
ballasts to a store owner that insisted on
using metal halide lamps on HPS ballasts.
However, the metal halide
bulb in this auction is specifically
designed to operate on an HPS ballast. It
will withstand the high voltage kickstart
that a sodium fixture delivers.
Please notice that this is
not a big honking bulb that is too
big to fit in your fixture. Standard 400
watt metal halide bulbs are like small
footballs. This bulb is about the same size
as a standard 400 watt HPS bulb. Most
importantly, the bulb’s arc tube is in the
same place. So a reflector optimized for an
HPS bulb will work great with this lamp!
Thanks for your interest.
