The good old incandescent bulb. Here we have both red and orange bulbs that give a nice night time glow. Incandescent bulbs have no blue light, very little flicker, no additional high frequencies and no dirty electricity. In actually fact, incandescent bulbs reduce dirty electricity by converting high frequency to heat.
 
These bulbs are becoming more rare, so get them in while you can.
Low 25 watt.
 
Orange bulbs are the standard E27 screw fitting.
Red bulbs are the standard B22 bayonet fitting.
