Hard to find, but once that was done...


The web site is not too well organized, and often appears to list the same bulb multiple times. Searches often don't take into account the type of base, making searches for unusual bulbs harder. Once you find it, the prices are better than competitors.

It's a light bulb. When u turn it on it is bright. When u turn it off it is dark. What more is there to say? Oh,I know. The description is wrong. The gap between the contacts is 1/8. Not 1/16".other than that everything works fine.


san diego,Ca.




I was so happy this came, and it worked! Put it in the lamp, and when I turned it on and the light shown out I was so happy I grinned for at least an hour. Sorry I'm not giving you the sort of review you seem to want, but I was just so pleased with the fact that the bulbs came as quickly as they did... and worked perfectly. I really couldn't be happier with the bulbs... or your company!

Best Deal If You Own A RV


Same bulb that cost over six dollars at popular stores. Same or better quality for our 5th wheel unit which is our home. I looked and looked and this is the best bulb and best price I found. Side by side with any bulb in our 5th wheel they perform the same or maybe even better. Very happy will tell others as we travel and work camp in different campgrounds.

Very Bright compact lamp


We used this product as a stand alone single source to simmulate a candle flame quite effectively.




great product, great price


Not often one gets both value and it!!




Better Than Expected Product


I had previously purchased similar bulbs at [@] and paid a lot more per bulb. The bulbs lasted less than a week. The bulbs from have performed exceptionally well, and have added elegance to our living room chandelier. The difference in the brightness and exceptional quality is incredible. And I saved money in the process. Thank you to all at And Happy Holidays!

Q & A
Is a bulb shape of 'JCD' compatible with my system which has 'T3' bulb shape lamps ?

Provided the wattage, voltage and bases are the same, the bulb types are compatible.

Product Support

Can I use this bulb in my Malibu outdoor 12v lighting system?


This bulb is 12 volts and may be a suitable replacement for the Malibu lighting system. We do recommend verifying the maximum wattage allowed for the fixture and also the base type. This bulb has a G4 base. The spacing between the two pins equals 4 mm. We would suggest measuring an old bulb to verify the spacing of the pins.

Yes you can Dave. Have used many times with malibu
