Light Measurement
The museum environment is a complex subject that cannot be reduced to a simple set of requirements. The enforcement of prescriptive and rigid environmental specifications can result in unintended and adverse consequences, both to the collection and to the overall institution. Although there are practical reasons why guidelines have transformed into rigid specifications, the emphasis needs to shift back to flexible performance-based guidelines.

It is important to understand how silica gels vary in performance in order to select the most cost-effective gel for a particular application. MH, the hysteresis corrected buffering capacity of silica gel, is the critical variable for assessing silica gel efficiency. Calculating the correct quantity of silica gel allows for the cost-efficient selection of an appropriate amount of buffering material. If certain variables in the calculation are unknown, such as leakage rate or external RH conditions, general recommendations based on average display conditions have been provided, both for temporary exhibitions and for permanent displays. Finally, simple procedures for the use and maintenance of silica gel have been described. Passive humidity control within an exhibit case, when applied correctly, is a very simple and cost-efficient method of protecting museum collections from humidity induced damage.

Light Emitting Diodes (LEDs) have been gaining a great deal of attention over the last few years. This interest has been fueled by the need to find an energy efficient replacement for the incandescent lamp, a technology that has been around in various forms since the time of Edison. The rapid emergence of LEDs as a potential source for general lighting applications has also led to a great deal of confusion and concern about the appropriateness of the current generation of LEDs.
