Supermarkets
Supermarkets present a demanding and varied environment for lighting equipment, especially where linear sources are called for. Areas over openly displayed products such as produce and foodstuffs require that the glass tubes of fluorescent lamps be covered with plastic sleeves to assure that accidental breakage doesn’t allow glass particles to fall into the foods. Frozen and refrigerated food cases are especially difficult to light efficiently. Fluorescent lamps are extremely sensitive to ambient temperature. If the wall of the glass tube is cooled, or heated, outside a tight range in the mid 70s, the light output falls off drastically…approaching 20% or even failing to no light at all. The sales areas can be well lighted by strip fluorescents but LEDs can allow for 50% energy reductions for the same light levels. For these factors and considerable energy reductions it is wise to convert these applications to LED tubular sources. LED lamps by CERTIFIED LED have a rated life at least four times that of fluorescent lamps and emit the same amount and quality of light as fluorescents, thereby creating considerable maintenance savings in both downtime and labor….and LED lamps do not lose light at higher and lower temperatures like fluorescents.
