The color rendering of a light source describes that source's ability to accurately
render the colors of perceived objects— people and things. As a general.
Color Selection Guide The color rendering of a light source describes that source's ability to accurately render the colors of perceived objects— people and things. As a general rule, the higher a light source's color rendering index (CRI) number, the better the lamp will make things appear. SP Lamps have CRI's of 70+ making them better color-rendering light sources than older, standard fluorescent lamps. SPX lamps have a CRI of 80+ for even higher
Great Color-Without Giving Up Light Specially developed rare-earth phosphors provide what conventional phosphors cannotboth high efficiency and good color rendering. Lamps made with conventional phosphors produced only 60-70% of the light of their standard counterparts. Now, in SP and SPX lamps, GE technology has produced colorenhancing fluorescent lamps that

Extraordinary color and extra color rendering options: Starcoat™ technology provides the best color rendering in the industry, giving furnishings, decor, and merchandise a true, natural appearance. Two color options—popular SP color (78 CRI) and deluxe SPX color (86 CRI)—help you make the right choice to meet your application needs.

SP lamps use a double coat of conventional and rare-earth phosphors for a moderately priced, good color rendering lamp SPX lamps use much more of the rare-earth phosphors for a premium-price, very good color rendering lamp Occasionally SP lamps may have SPX type color rendering or 80+

A WARM TONE:
SP30—Especially good for low light levels. Use where you want people and furnishings to look good.
SPX30—Warm, but brings out high color contrast. Especially good for low light levels where colors must look very good - dining areas, exclusive stores etc.
A MODERATE TONE*:
SP35—A tone acceptable to nearly everyone. Good for nearly any application where you want people and furnishings to look good.
SPX35—Moderate tone acceptable to nearly everyone. Brings out colors strongly. Especially good for all kinds of merchandising and areas such as executive suites, conference rooms. Use wherever colors must look very good.
A COOL TONE:
SP41—A tone similar to cool white, but better color. Especially good for higher light levels wherever people and furnishings must look good.
SPX41—Cool tone and very good color. Renders all colors well, but emphasizes blues and greens. Use for offices, merchandising areas, and color-important industrial applications
SP50 and SP65—A tone similar to Daylight lamps, but more efficient.
SPX50 and SPX65—Provide a unique crisp clean look and blend well with outdoor daylight. Use for daylighted spaces, industrial clean rooms, special retailing and commercial areas. Renders all colors well, but emphasizes cool tones. May be too cool for some applications— especially at low light levels.
A VERY COOL TONE: (DAYLIGHT-SIMULATING)
*The moderate color temperature of the SP35 and SPX35 is usually acceptable to those who like warm or cool environments. These colors are also useful for well-shielded lighting systems (wedge louvres, deep-cell parabolics) which tend to "cool off" the space visually.

1. Watt-Miser , Watt-Miser Plus and Energy Efficient (/EE) lamps are intended for use where ambient temperatures are 60°F (16°C) or higher and where the lamp surface is protected from strong air drafts. Failure to protect the lamp surface may result in reduced life, poor starting or erratic operation, such as flickering or spiraling. All T12 Watt-Miser® lamps are intended for use on two-lamp, indoor, lead, high power factor ballasts and are not recommended for use with dimming or reduced current systems. The use of T12 WattMiser® lamps on single lamp ballasts may shorten lamp life. T12 Rapid Start Watt-Miser® lamps are intended for

use only with Rapid Start Ballasts. F40 Rapid Start WattMiser® lamps on high frequency electronic systems may display erratic starting before end of life. T8 Watt-Miser® and F28T8/UMX lamps are intended for use only with instant start ballasts. F28T8/UMX lamps achieve optimal performance on GE UltraMax™ IS ballasts.
12. Do not use CovRguard® HO lamps in watertight or airtight fixtures.
4. Because Power Groove and Very High Output lamps are most used in commercial applications, the life rating is based on 12 hrs. per start.
16. Life rating is based on UV maintenance curve and is measured at 80% of initial (100hr) UVC output.
