CTKcom 250-Watt 3.1-Inch T3 Halogen Bulbs(5 Pack) - J Type 78mm Double Ended 120 Volts 250 Watt T3 Halogen Bulbs R7S Double Ended Filament Flood Lights Quartz Tube Lamps 120V,5 Pack

All bulbs arrived in great condition none broke , both that i have installed work as and how they should , people need to remember these are not normal bulbs and gloves should be used to handle and install them , preferably wipe them down with an alcohol wipe after unpacking, the oil on skin reacts with the glass and will cause premature failure , i have no complaints about these bulbs

These bulbs will light up your life. My fixture has low and high settings and these bulb work great.

Great price fast shipping

Bulbs fit perfectly and are a nice bright white. Only problem was that one of the five bulbs was broken and did not light up!

Two blew out right away, but the next two worked well. Thanks

It's too soon to know how long these will last in actual use at this time. However, these fit perfectly and and are nicely packaged. I have a couple of quartz-halogen work lights kits that I purchased almost twenty years ago now. They consist of a multi-piece adjustable stand with light fixtures, all in a compact carry/storage case. I used them more times than I can count and have loaned them to neighbors and friends over the years. The only problem I've had is finding replacement bulbs locally, as these are only 250 watts and not the more popular 500 watts bulbs that local suppliers usually have in stock. But I like these 250 watt units as I generally don't need the hotter bulbs and this offering from CTKcom was perfect. Each bulb is individually wrapped in a small protective plastic sleeve and inserted in an equally-sized cardstock box. The bulbs are standard sized at just over three inches in length with white ceramic ends that fit into the usual spring loaded worklight receptacles of this type. The glass filament tube is crystal clear, very well made, and the fillament itself appears to be quite sturdy. Generall speaking, failure of this type of bulb usually happens when the lamp is knocked over or falls in some matter, often breaking the bulb. These particular bulbs appear to be constructed in a manner to protect from easy breakage. One thing to note for new users, is that you should not touch the bulbs with your bare fingers, as the skin oil or dirty print on the glass tube may cause an irregular hot spot that will cause uneven thermal expansion and increasing the chance of breakage. (That has nothing to do with the quality of manufacture, it's a failure in handling of any heated bulb of this type.) Great price, well made, and a good quantiy to have in your back-up stock. Thanks CTKcom.

Extremely low quality. 1. The length is SHORT! 76mm not 79! It's shorter than US made bulbs my standard US made light fixture is accepting. I had to bend fixture contacts to reach the bulb sockets! 2. One bulb died on the first day! It was also too bright compared to the second one I've installed in replacement. Obviously defective bulb with short-circuited coils in the spiral (but the bulb looked OK initially). Four more bulbs to go... Prepare replacing them often due to above factors. Nothing like my prior bulb which served for 3+ years.

Bulbs work as intended.

It was getting hard to source these bulbs locally. These install easily and light well. Quality seems good. Time will tell.

Worked flawlessly

3 of 5 bulbs burned out after just a few hours of use... past the return window now.
