Paint booth lighting: candlepower, local codes, fixtures, bulbs


Q. With the push on to reduce VOC emissions and the lowering of LEL levels in a paint spray booth setting, does anyone have any information on how this will impact the manufacturing processes of the light fixture manufacturer, e.g. UL, ETL, NFPA, etc.?

Gary Fenner

A. I see an average of 2 different lighting manufacturer's parts come in my department every week. The reason is they are moving from solvent based paints to different finishes. Some are using powder, some are using new waterbornes. Whenever you change your process you have so many unknown variables to account for. Most companies I have talked to find this an excellent time to test new coatings, colors, and equipment and eventually revamp their whole process. In a brighter note,these more stringent regulations sometimes give companies the chance to review their current needs at the same time as they are working toward compliance. -Tim

RFQ: To Whom It May Concern:

I would like to get some information on Paint Booth Lights.

I am trying to find hazardous location lights to meet the City of Washington Codes. If possible please contact me. I really would appreciate it.

Thank You

Q. The local fire department is requiring me to upgrade our auto paint booth with some type of 4 bulb fluorescent explosion proof lights.

I need help in determining which lights are suitable and where I can get what I need at a reasonable or best cost.

Thanks for your help.

Q. I am interested in learning more about paint booth lighting. Our painters insist that they need something better in the way our paint booth is lit. I presently have measured 126 foot candles at the work surface, but at a later inspection we still find places that require touch up.

A. David,

One idea is what I have used (I do assume that your paint could be sometimes 'lacquer', i.e., somewhat explosive) in very strong acid fumes in special fume hoods.

These had twin fluorescents externally shining through an ordinary glass (not tempered, I mean) plate. The fluorescents and electrics were obviously NOT in the airflow! The glass plate could be, were it necessary, easily removed for cleaning.

In your case, think of coming up with a simple 'box' angled in at perhaps 45 degrees with said glass plate (but held in situ by some rudimentary clamps) into which the fluorescent ballast and lights fit in click-click.

Simple. Cheap. Prevents painters from swearing at you! And you'd get a better job done.

NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials

August 5, 2008

Q. Hi there,
I need to know if there are lighting requirements that can be measured by a light meter for industrial painting (industry standards)?
I am developing a quality assurance program for our paint shop and want to set a stringent lighting requirement that will let us know when we need to clean or replace the lighting in our booths.

Q. Replacing the fluorescent lights in our parts paint booth with the newer fixtures for T8 4 foot bulbs. There are as many varieties of this bulb as there are paint colors. Just looking for some advice on which T8's bulbs to purchase?

A. As far as color goes, the lamps in the 5000 Kelvin range will give the appearance of more light.
You will also want a higher output lamp.
GE's version is the F32T8SPX50
Phillips lamp would be F32T8 850 eco.
There may be others.
