Scope of Test Determine if UVA lamp light energy (mW/cm2 or Joules) diminishes as temperature continues to rise outside the optimal operating parameters. According to most UV lamp manufacturers the optimal operating temperature for UVA lamps is 108ºF. At 120ºF it will diminish by 20% and at 140ºF it will diminish by 30%. This is … Read More...
