Question

Low pressure sodium and linear fluorescent lamps tend to have long life and very good lumen maintenance. Incandescent lamps have good lumen maintenance but shot life.

True or False?

Answer 1

False. Low pressure sodium and linear fluorescent lamps have longer lifespan and better lumen maintenance compared to incandescent lamps.

Step-by-step explanation:

False. Low pressure sodium and linear fluorescent lamps have long life and good lumen maintenance, while incandescent lamps have shorter life and lower lumen maintenance.

According to the information provided, LED bulbs have the longest lifespan of 50,000 hours, followed by CFL bulbs with a lifespan of 8,000 hours, and incandescent bulbs with only 1,200 hours. LED bulbs are also more durable and can withstand rough treatment compared to incandescent bulbs. Additionally, CFL bulbs have less heat transfer and last up to 10 times longer than incandescent bulbs.

Based on these facts, it is clear that low pressure sodium and linear fluorescent lamps have better lumen maintenance and longer life compared to incandescent lamps.
