15 Watts T7 Replacement Light Bulb for Lava Lamp 15T7 Incandescent for 10 Inch Lava Lamps and Exit Lamps and Sewing Machine Light Bulbs Fits E17 Socket 130 Volts Pack of 6

I just received my 15 watt t7 tubular light bulbs. These have the intermediate base. These fit perfectly in my very small lava lamp brand lamp. I ordered another set with a candelabra base, but it was too small to fit. You can see the bulb is working, and I have plenty of spares. I cannot speak for their longevity just yet. However, I do track how long my light bulbs last by writing the installation date on the bulb base. So we will see? Oh, and the package arrived 2 days ahead of schedule

Bought these lights for my sons lava lamp. The lamp isn't the biggest one just so you can have a idea but the light bulbs work great my son uses his like a night light and each bulb last about 3 months or longer but there is plenty of bulbs so its worth it

The bulb is an adequate 130v, 15w, long life bulb. This is just poorly suited to create enough heat to melt the wax to make my lava lamp function. So, it's a good bulb for creating light, but, I don't think it should be advertised as proper equipment for lava lamps.

Best bulbs for your lava lamps

I wanted to replace my 20w microwave bulb that i use for a kitchen night light and found these 15w which are even better for my purposes as they have the perfect level of low glow that I wanted. You cant beat the price for 6 bulbs either.

I used almost all of them in my Lava lamps.

I bought these for my small lava lamp but will barely get the wax flowing. The wax just gets to the point of a tower from the bottom but not moving to the point of balls rising and sinking like the older original 15w bulb would do. They do light up and may work just fine in a night light but not good enough for my lava lamp at least.

The bulbs work and were more reasonably priced than the store.
