+40 To compare the efficiency of each bulb, calculate how many lumens each bulb produces per watt. To do this, divide the number of lumens by the wattage for each lamp.** Include all units.
The table is as follows:
| Lamp | Lumens (lm) | Wattage (W) | Lumens per watt (lm/W)* |
| Incandescent | 800 lm | 60 W | 13.33... lm/W |
| Halogen | 6,000 lm | 300 W | 20 lm/W |
| Fluorescent | 2,000 lm | 30 W | 66.66... lm/W |
A. Which lamp produces light most efficiently?
B. Which lamp is the least efficient?
**The thing about this is I get answers I'm not sure are correct. I don't know if I carried the problem out the right way or if I misread
*The "unsure" answers that I got
+37159 To get lumens per watt (l/w) just divide the lumens by the watts
You have the correct answers......the most efficient one will be the one with the highest l/w number (66.66 l/w)
Least efficient is smalles l/w ( 13.33 l/w)
