These are fairly new and in great shape but still in used condition (about 5-6 yrs old). High/low bay 350 watt pulse start Metal Halide fixtures.You are bidding on one complete light fixture. I have more available if you need more just ask me.They also come with a used bulb which costs $32.00 new. I’m selling the whole fixture for less thana new bulb would cost by itself. They will also come with a open acrylic diffuser/refractor lens the kind you see in Sam’s Club and Costco store’s. This will force 90% of the light emiited by the bulbdownward.

These are made forwarehouse or manufacturing lighting applications or maybe even a large fishtank growing coral reefs. These are great for any type of plant growing situations either in containers indoors or hydroponic gardens. These will give off a lot of light in the blue light spectrum band which is ideal for vegetative plant growth. These lightswill grow strong bushy plants and with its abundant red or orange spectrum light emitting qualities there is no need to change bulbs all the way through the flowering stage of the plant cycle.

If you need more fixtures just ask me for my great shipping discounts!!!!! On multiple orders. I will only ship to the lower 48 states.

BELOW ARE MORE DETAILS OF THE ADVANTAGES OF THIS NEW TECHNOLOGY

High Efficiency Pulse Start Metal Halide Acrylic Prismatic Refractor Light

Get More Light with Fewer Fixtures and Less Energy!

Pulse Start bulbs make 30% to 45% more light than their conventional metal halide counterparts. State of the Art Prismatic Refractors deliver an extra 20+% light. You get a total of 50% to 75% more light using 10 less watts!!

This fixture replaces 1.5 standard start metal halide low bay fixtures, but uses 260 less watts to do it! Over the 20,000 life of a pulse start bulb, that’s a $545 energy savings per pulse start prismatic fixture!

($.10/Kwh assumed)

LOWER INSTALLATION COSTS

The Spartan Pulse Start ballast with its lower starting and operating current ratings, allows up to 17% more fixtures per lighting circuit. This results in significantly lower labor and material costs for new or existing installations.

Pulse Start Bulbs Start Out Brighter and maintain 80% of their initial light output at median life. Common metal halide bulbs only maintain 65% of their initial light output at median life and keep losing output.

When combined in an Pulse Start fixture, the

new lamp and ballast technology delivers a 75W

savings per fixture when comparing the 350W to the standard 400W. This results in approximately $58 per fixture in lower annual operating costs.

( Comparison of 350W vs 400W at 10¢/kwh for continuous operation)

The 350W Pulse Start lamp was originally designed to replace the standard 400W lamp for any application. It is a long life, highly efficient lamp that will maintain higher lumens and faster re-strike

and warm-up than standard 400W lamps. Available for open and enclosed applications. A long term high energy saver.

BALLAST

TECHNOLOGY

LONGER BALLAST LIFE

Heat is the natural enemy of all ballasts. The reduction of

40% of the ballast’s heat will increase its service life in typical applications. This new Spartan ballast technology reduces not only the power used by the lamp but also the power used by the ballast itself. When compared to standard 400W ballasts and their 60 watts of ballast loss, the 350 ballast and its 35 watts of ballast loss, represent a 40% reduction in ballast energy consumption.

Which equates to;

– A permanent 20-30% reduction in energy costs for the same lumens

– A 20-25% higher light level

Added advantages of this fixture!!!

There are some really bad high/low bay fixtures around. They catch flies and dust that get trapped inside! The debris settles on the bottom lens and blocks your light. Once it gets inside, dust sticks like a magnet to the reflector andclouds it! These acrylic prismatic refractor does not have this problem as the bottom is open. The refractor also serves as a thermal chimney that induces convective air currents to naturally cool the bulb and ballast!

OPEN LENS RATED BY UL;

Underwriters Lab requires the standard metal halide low bay lamp to be operated in fixtures that have a bottom lens for containment because of the possibility of rupturing of the arc tube at end of life. This protective quartz shroud allows most of the Pulse Start lamps to be open rated. This is another advantage of this fixture.

Prismatic Optics are the Best

Theywork in BOTH HIGH and LOW BAYs

The prism on this fixture makes it superior to either conventional High Bay or Low Bay fixtures. By scientifically bending light down, this fixture will deliver higher light levels on the horizontal plane than high or low bay fixtures. At the same time it produces very good illumination on vertical surfaces.

“High bay” fixtures normally have spun aluminum reflectors that must be hung very high. If they are hung low, they only produce a little pool of light on the floor. About 23% of the light generated by the bulb is trapped in internal reflections.

The optics on “Low Bay” fixtures are really high bay reflectors that are “wrecked” with white paint. The white paint and lens helps scatter the light. But the white paint further destroys the efficiency of the fixture. Light is trapped rattling around inside of the fixture. Only 74% of the light produced by the bulb actually gets out of the fixture.

These fixtures with the acrylic prismatic refractors deliver about 90% of the light of the light produced by the bulb. While at the same time, the horizontal utilization coefficient, the ability of the fixture to direct light on a horizontal plane, is higher than a typical high bay fixture.

Most importantly the patented prismatic refractor delivers “3-D” illumination.

“3-D” Illumination Keeps you from working in a Cave!

The problem with conventional metal halide fixtures with metal shields is that they just put pools of light on the floor. Little light is cast on vertical surfaces. So in a repair shop, you can’t see in wheel wells. Or in a warehouse, light is not shed on the vertical faces of pallet racks.

Conventional metal halide fixtures create a cave like atmospheres with dark ceilings and walls.

These fixtures prismatic refractor bends light down from the ceiling in all directions. So you can see everywhere you look! Excellent uniform lighting is produced! It makes indoor spaces appear larger and more spacious.

Achieve Uniform Lighting with Larger Fixture Spacing.

A standard type of low bay or high bay light mainly directs light straight down. So the highest light levels are produced directly underneath the light fixture. You see, light levels approximately drop off according to an inverse square law. So when you get twice the distance from a constant source, the light level is only at 1/4 intensity. So light levels drop off steeply as you get further away from the fixture.

How far do I put the fixtures apart?

How many do I need?
People looking for minimal light levels to see by have put this style of fixture 80’ apart. The prismatic refractor on this fixture has a semi-indirect light distribution. This means about 20 % of the bulbs output bounces off the ceiling and upper walls. This scatters light all over the place. So you don’t have dark shadowed areas.

The main beam of this fixture is in an approximate 50 degree cone. This beam spread is adjustable. So this fixture will very nicely light up a circle 2.3 to 2.8 times the mounting height of the fixture. But normally, you don’t have to concern yourself with this. Usually the number of fixtures is controlled by the light levels you are shooting for.

With most practical fixture layouts, the number of fixtures you need depends upon what you are doing in the space, how reflective room surfaces are, and a height aspect ratio.

Otherwise, here are typical light levels produced in foot candles (fc)

24’x 48’ w/4 fixtures @ 16’high

Dirty White Walls……….62 fc
Unpainted Wood Walls….51 fc
or Foil Back Insulation

40’x 40’ w/5 fixtures @ 16’ high

Dirty White Walls……….62 fc
Unpainted Wood Walls….51 fc
or Foil Back Insulation

80’x 120’ w/24 fixtures 23’ high

Bright White Walls………75 fc
Dirty White Walls……….60 fc
Foil Back Insulation……..58fc

It’s generally advantageous to hang fixtures as low as possible as this will increase average light levels. The lowest mounting height I’d recommend is about 12’ high.

To get even lighting you generally will want to run staggered rows where the fixtures in one row fill out the “holes” in the others. See example.
