5Pack - 78mm J Type Double Ended T3 Halogen Light Bulbs, 120 Watt 120 Volt (150 Watt Halogen Bulb Replacement), Energy-Saving 20%

All five bulbs arrived intact, no breakage in shipping. I tested each bulb and all worked just fine. I wanted to test the four I would be storing so that if I needed any replacements I could get them now. I am very happy with my purchase, so much cheaper than what I could get at a regular store, pls it was delivered right to me. Obviously at this point I don't know how long the bulbs last compared to other brands. Each bulb came in it's own little box, inside the box the bulb was in a tiny bubble wrap sleeve; all all five were wrapped together and placed in an amazon box with the big puffy air pillows.

easy to install. fit out uplighting perfectly and is much brighter than the old bulbs. Now we can rock the suburbs in style.

They are very cheap (deal) and work. What else to say, not for the audiophile.

These are standard 78MM bulbs. Looks well when I received it. It has 5 bulbs in a box. As the seller described, it can be used for at least 2 years no more the 3 hours in one day. I don't know the fact, because I don't use it for that a long time. Hope it can be used as ideal. You can actually install this type of bulb in the light without making proper contact with the connectors, which is often the reason for new bulbs to seem DOA or blink. When older bulbs start to blink, it's a good sign they are about to fail. These bulbs seem to be of good quality and none have been DOA. Nice to get 5 bulbs for total price $10.

These bulbs are junk just like everything from China. I use these in a shop light that is on a couple hours a week. Maybe 10 hours a month, two bulbs at a time. In ten mknths I have gone through these 5 plus on more. I think we sould expect more life than 40-50 hours. Someone using a fisture an hour a day could expect to replace these two times every three months

The bulbs are good. I am not sure how long they will last (my 100w Philips seemed to last like forever on dimmers), these are 120w and I dim them even more so technically they should last even longer but you never know what comes from China. In comparison to 100w 2700k Philips, these are brighter and a bit more whiter so I think 120w and 3000k is accurate. PS. I replaced working bulbs because I wanted more lightPS. Keep in mind that 120w will run hotter and most 100w fixtures are rated for 100w bulb heat. I personally dont think that extra 20w can do any damage but just putting it out there. Lets just say I wouldn't run 150w in a 100w fixtureEdit: lasted only 1 year on a dimmer, I expected at least double that.....

Just installed tow new bulbs in my motion lights, the factory bulbs that came with the units burnt out in less than a year. These work well so far, easy install. Use gloves. Hope they last a while.

Not sure how long they last yet, but they seem to be of the same quality as the others I've found on the market. Very delicate ends though. But that's how the pricier ones are too.
