if they are connected in parallel only(provided circuit terminal voltage kept constant throughout ).
Bulb filaments are designed illumination point view (with tunganstn metal filament) such that, more the watt consumption more would be the illumination or 120W would give more light(double) than 60W, for same supply voltage rating.
If by light you mean illumination then the answer is no ..
For a tungsten light bulb : the size of a single 120w is 1.5*the size of 60w, so even if you kept the two 60w bulbs close together, the lux concentration will be less than that of the 120w, so the two bulbs will cover more area with more uniformity in lux
hi
Check the lumen ratings for the two 60 watt bulbs, and compare it with the lumen rating for the 120 watt bulb. That should give you the answer you seek. The 60 watt bulbs may give off a light that is more yellow than the 120 watt.
Two 60 watt bulb deliver more light than a single 120 watt bulb.
Yes.
Two 60W bulbs, each driven independently, deliver the same light power as one 120W bulb.
(but if one wants to get finicky, the 120W bulb is a smidge brighter, as the base of the 120W bulb (which is opaque) is not twice the area of the 60W bulb)
40 Watt incandescent lamp produces only 380-460 lumens and uses 40 Watts of energy per hour.
100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour. - See more at: http://www.sepco-solarlighting.com/blog/wattage-vs-lumens-know-the-difference-for-better-lighting#sthash.voPVMNhH.dpuf
