Lava the Original 501012 Lava Lamp 100-Watt Replacement Bulb

The media could not be loaded. Works great! We have the XL lava lamp and the original bulb burned out in less than a year. No local stores carry a replacement bulb because most stores carry LED that doesn’t produce heat which makes the lamp work. We bought this based on a wonderful review on this bulb from another person who bought it and it works great.

We bought a big old lava lamp and this fit in it perfectly.

As you can see in the images, the old bulb (frosted) and the new are dimensionally almost identical. The Amazon bulb, the one on the right side, comes in a plin white box. Some people may be put off by this, however, in these times of LED-only, I’m not picky. Also, it is clear and not frosted. For a lava lamp application, this should not matter. What matters is that it is: 100 Watts, incandescent, reflector, and is reasonably close in size. I measured the amount of space the lamp has for the bulb. Even if the bulb were a half inch longer, it would still work fine and not be crushed by the globe. I wouldn’t want the bulb to get much closer than that.I plan to convert all of my lava lamps to LED RGB ring lights using ceramic heaters. I acquired a reptile heater that screws into the socket for this bulb. I realized that I do not know how much heat I need from it, so I am going to perform a scientific experiment to acquire the daya I need for actual heat output from the light bulb I just acquired. Then I’ll compare outputs to different Wattage heaters. I’ll then use an inline dimmer to further tweak the heat to just the right amount. I believe it will be useful to use the dimmer to lower the amount of heat once the wax gets flowing.My next step will be to add an LED RGB ring light with some kind of heat shield for them.After that I may use an Arduino or equivalent to control both the heater and the lights.In the mean time, I’ll have my grande lava lamp entertaining me nightly.2024-03-20 Update: I found the exact same replacement bulb at a respectable retailer who acquired several directly from Lava Lamp, same price. The box is the third photo with the same bar code and plain white box. Apparently Lava Lamp changed the packaging.Also, I discovered that they now offer a small candle powered lava lamp!

First bulb came shattered. Got a replacement, that one came shattered as well two for two. The product packaging does not protect the bulb whatsoever. On top of that the first bulb was delivered in a thin plastic bag. Second one in a box but still in a million pieces. The manufacturer needs to make the packaging more sturdy to protect bulb and Amazon needs to have neon orange or pink "FRAGILE" stickers on bulbs and fragile items. We have a third one coming today, we'll see if this one is in one piece! Update 8/23/25 third bulb arrived shattered as well. That's three for three! See picture of all three broken bulbs. The manufacturer needs better packaging. No protection for these bulbs whatsoever.

Works perfect for my extremely large lava lamp. The first one arrived broken and they shipped me another right away. No questions asked. Thank you!

Got my grande flowing again, but do note that the one I received is transparent on the top with a silver reflective surface underneath, not the fogged one like in the product photo.

works great for my large Lava Lamp.

I got an off brand light bulb for my lava lamp last time around. Idk why exactly. I was not pleased with it. I thought my lamp may be messed up but after buying this bulb I’m happy with my lamp again. It’s the 27 inch original one btw
