PAR and BR bulbs share the same voltage of 120VAC and have the same Kelvin degree color code as all light bulbs: 1  2700K (warm white). 2  4100K-5000K (cool white). + 3 5000K (daylight color).
Wandering baseline is signal noise or artifact on an ekg caused by loose connections, patient breathing, etc. .. But nothing to do with the activity of the heart. In brief: Not to worry. Wandering baseline is signal noise or artifact on an ekg caused by loose connections, patient breathing, etc. .. But nothing to do with the activity of the heart.
1 If fact, attenuation and scatter actually distorts the acquired data making quantification difficult.  As an example, in PET brain <40% of the photon actually make it out of the cranium. The reason for this is the fact that gamma rays have to travel as much as 10 cm in a fluid media. This media attenuates and scattered and absorbs the photons being emitted.
