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.
