ConclusionConclusion

Warmer temperatures registered Warmer temperatures registered higher lumens than lower higher lumens than lower temperatures on average.temperatures on average.

Industry using chemiluminescence Industry using chemiluminescence may want to adjust temperatures to may want to adjust temperatures to reach an optimal temperature for reach an optimal temperature for amount of light (lumens) like in the amount of light (lumens) like in the use of blood detection in forensics.use of blood detection in forensics.
