- There is no bio hazard in a broken LED lamp.
Lamp life is generally determined based on what they call "Rated Average Life", which means that they turn on a crap load of lamps and when half of them burn out, that's the average life of the lamp. This is usually the way the life of fluorescent lamps is determined. LEDs actually never burn out, they just lose light output after a while and need to be replaced.Apr 18, 2012
- When trying to decide whether to purchase LED lamps, you generally want to look at the total hours for each lamp burned in your house.
20 lamps x 60 watts x 1 hour = 1200 watts of energy each hour the lamps are illuminated. Now take that number and turn it into 9 watt LEDs and you can calculate the cost savings. It doesn't usually appeal to people when looking at the cost of one LED lamp, but changing them all in your house, over the course of a year, you're saving a significant amount of electricity cost in just your lamp usage.Apr 18, 2012
- Even if they hit the $20 retail sales point, it still too much. a 13 watt CFL with similar output is under $5. If the LED's energy usage was around 6 watts and the price was around $15, it would be worth the initial investment.Apr 18, 2012

- I have a couple at home. I like the light, could be brighter though. I took out all the CFLs from my house.
I was getting migraines and the doc asked me if I had any CFLs in the house? I work from home mostly with three laptops going at once. In the basement where I have my LEDs I had no migraines, but in the upstairs office where I had CFLs - migraines. I replaced them all with incandescent bulbs and no more migraines.Sep 6, 2012
