    very good price for 300 watt
  

*by A***T on Reviewed in the United States on October 15, 2015*

I had been using Fiet electric halogens and had noticed their bulbs weren't always consistent in quality especially those with higher wattage. Some would last a month, some half that. I use these in a security light for my back yard and if I am going to be changing them out every 2 to 4 weeks, why spend 7 bucks per bulb to do so? I haven't used these long enough to compare with Fiet hence the 4 stars assigned. In my experience, there are a lot of things manufactured today that don't last as long as they use to and light bulbs from a lot of companies have proven to be short lived. I just put a 60 watt Sylvania in my kitchen less than 2 weeks ago. It died yesterday. The Anyray halogens I tried for my front yard security lighting are always burning out. You can count on 2 weeks top with that brand. Hopefully Triangle will be a bit more reliable. I really wish I could announce the perfect long life bulb for all those people just like me who are tired of throwing away money on something that leaves them in the dark. Trouble is, I'm still looking and you guessed it, doing so in the dark. My question is, who supplies  the bulbs for prison yards, airports and big mall parking lots and why can't the average consumer get access to bulbs of equal clarity and life??Update 3/5/2017:  I'm still using these and have gotten some reasonable mileage out of this brand burning my deck light from dusk to dawn every night. And by reasonable I mean approximately 4 to 5 months per bulb on average.  Very satisfied and I will be ordering these again. they are a bright white and light up my 45 x 50 Ft backyard very well even in some intensely inclement weather.

    May not be ideal replacement for everyone
  

*by G***B on Reviewed in the United States on December 7, 2014*

The product works and it is cheap when looking at comparable items for this model light. However, there are certain drawbacks with this one. Most important of all is the light intensity. It is no where near the intensity of light I am used to with the previous bulb. So, 300W light output is questionable. If you try to use it for dimming, you will get some noise. So, it is better to use it at full intensity which anyway is already less bright. Since I am not a photography person, this is okay for me. The bottom-line is that this is not a perfect replacement, but will be just enough for some people.

    Worst bulbs ever, you get what you pay for....
  

*by C***N on Reviewed in the United States on January 29, 2013*

I can't believe how bad these bulbs are. I decided to try them to save money since we're on a tight budget but the moment you put these bulbs in you wonder where the light is. They are about half as bright as normal bulbs and in the 4 months that we've had it in the lamp, it's managed to get continually darker and darker in here over time. When I could no longer read anything clearly and decided it felt like we were living in a vampire cave, I finally decided to try another brand of bulbs that I had purchased before by Feit Electric. 3 bulbs for $8 is a little more expensive than the 5 for $7 we paid for these (including S/H) but well worth it in my opinion. I couldn't believe when I took the bulb out of the lamp, the glass tube was almost solid black with filth covering the entire inside! I took a picture to show what it looked like. No wonder it was getting darker each passing day! I feel sorry for the poor sick light bulb having to strain to produce light through the glass and the fact that it did actually produce SOME light for a few months gives it another star, but that's as far as I go. Buy another brand, it's just easier and will save you time.
