The Old Grey Whistle Test
Some suggestions to keep in mind when planning a detailing bay layout



Ceilings: twelve-foot (12') ceilings and a ten-foot (10') door opening should accommodate most vehicles. Two twenty-five by twelve foot (25’ x 12’) bays and a twelve by thirty foot (12’ x 30’) office/storage space for supplies, this will enable one dry and one wet, one should have a floor drain with holding tank and one should house a forty eight inch (48�) scissor lift.



Walls: Interior Acrylic enamels with a low lustre sheen (Reflects well but not blinding) and provides a very durable/ washable surface finish over a good quality primer.



Floors: Fill in any cracks and remove old paint etc, etch concrete surface with muriatic acid before applying two (2) coats minimum



Wall Base Moulding: To seal the floor/wall and provide a practical waterproof finish (apply to wall with tape



Storage: use less space to store more with high-density Stanley® Vidmar® cabinet systems. Far more storage-efficient than open shelving, modular drawer cabinets are custom-built to your exact needs; height, width, colour, number of drawers, drawer layouts, and etc, all units carry a lifetime guarantee



Power: Dedicated 20 amp circuits (with GFI) for the Air compressor, pressure washer, and carpet extractor, with overhead retractable power outlets for polishers and buffers.



Lighting: florescent lamps come in hundreds of different lengths and widths, but the most energy-efficient lamp is a T-8, which is a one-inch diameter tubular lamp. T-8 lamps are rated at 32 watts compared to the 40 watt rating of T-12 lamps, and yet provide the same level of illumination. The T-8 lamp has a CRI of 75, which is a 21 percent improvement over the old T-12s. This means that colours should appear truer to sunlight under the T-8 lamps.



Chromaticity refers to the pattern of visible wavelengths of light emitted by a bulb and is measured in degrees Kelvin (K). Most lamps fall in the range of 2200-7500K. A 2200K lamp creates a visually "warm" atmosphere that appears pink-red, while a 7500K lamp creates a "cooler" bluish tone. The T-8 lamp has a chromaticity of 3500K, which is considered to be visually "neutral," resulting in improved colour rendering for most general office work.



A combination of T8 florescent (general lighting) mount them overhead and angled on the side walls; use a separate light switch so you can turn these off when using surface inspection lights and halogens (spotting blemishes) on the walls spaced at approximately 36" centres, with 1000 watt twin halogens as for closer spot inspection.



Lighting levels of 100-foot candles at workbench height (42� from finished floor) recommend metal halide lights (175W -4250-5000 0 K, IT provides a ‘warm’ bright white light) over each detailing bay plus incandescent lighting on separate switch as metal halides have a delayed start, plus Daylight (Windows/skylights) if possible



Light output reduces from its source by an inverse square law; the table shows that fluorescent or incandescent lighting is more suitable for general lighting. Light output is measured in lumens, a typical 100W bulb produces 1700, a 175W metal halide bulb 14,000. The lighting available at the source is measured in foot-candles



T-8 colour rendition (CRI) values are much higher than Metal Halide so colours appear much more natural, they are also very energy efficient. They have electronic ballasts and are able to "instant start" in much colder ambient temperatures. When a lamp reaches end of life the other lamps will continue to burn so that the fixture continues to produce light until the old bulb can be changed.

Not sure where your information on this came from but it's incorrect; there are a wide variety of T8 lamps with different CRI and chromaticity (color temperature) ratings.
