Uses 43 watts to produce a light output of 750 lumens, comparable to the output of a 60 watt incandescent bulb; 2850K color temperature. A19 bulb shape; E26 medium base.Click to see full answer. Similarly, what is a 43 watt bulb?620-Lumen output and 43-Watts used, Lumens measure brightness of a light bulb, Watts measure electricity used to create light. Saves Energy – has similar Lumens(light output) as a standard 60-watt but only uses 43-watts.One may also ask, what is the equivalent of a 40 watt bulb? Equivalent Wattages and Light Output of Incandescent, CFL, and LED Bulbs Light Output LEDs Incandescents Lumens Watts Watts 450 4-5 40 750-900 6-8 60 1100-1300 9-13 75-100 Secondly, is there a 43 watt bulb? 43-Watt Halogen A19 Double Life Dimmable Light Bulb (4-Pack) Operating on a halogen capsule, these lamps offer all the benefits of halogen technology: true color (99+ CRI), instant-on, are fully dimmable and mercury free with energy savings that meet Federal EISA 2007 requirements.What’s better 40w or 60w?for series connection current is same. And resistance of 40w is higher than 60w means power dissipation is higher in 40w. Hence 40w bulb will glow brighter. For parallel connection voltage is same then power dissipation is higher in 60w means 60w bulb will glow brighter.
