We observed a strong correlation between conversion and the power of the lamp. The higher conversion being observed for the 32 W lamp vs. the lower power 18 W. Conversion rate was not correlated with temperature as we again observed a higher temperature of the photo-CDR reactor with the lower powered lamp and yet saw less conversion to brominated product. Future work could involve an investigation into the lux at the photo-CDR for different lamps. Clearly this would involve adapting the lamp holder to be able include a suitable type of illuminance meter (lux meter) and this is beyond the scope of this paper. In this paper we focused solely on the temperature profile of 450 nm blue lights that were relevant to the chemistry that we were performing at the time. A further study calibrating the air-cooler for lamps of different wavelengths would extend the scope of the reaction chemistry whilst maintaining control of temperatures for each given wavelength. Again, an investigation into a range of wavelengths is beyond the scope of this paper.
