Just bought a new 27" Lava Lamp. It is blue and green. I bought a red and purple one last year, and while it was not cloudy I had a similar problem finding a bulb to fit it.
I cannot find the medium base R20 100 watt bulb with a clear face.
For both units, I had to disassemble it and cut off the bulb stem 1.5 inches so I could put a normal sized bulb in it.
So I have tried different bulbs in it- some are too hot, others are ok but do not kick out enough light. I even put a dimmer on the cord and put in a 150 clear incandescent bulb. I adjusted to a nice level of action, but then the light was not as bright as it could be.
Someone help me out!
The 100W R20 bulb originally for the 27" (Grande) lamp is a frosted bulb. I have never seen a clear 100W R20 bulb, every Grande lamp I have seen has had the frosted bulb. That being said, you can purchase them directly from lava lite's website, or from Spencers online. I like to order bulk; last time I ordered 7 bulbs so that I do not have to order more for a very long time, as they sometimes are difficult to find. It also qualified for free shipping! Anyways, hope this helps!

There is also a Ebay option here: http://www.ebay.com/itm/391343035892?_trksid=p2060353.m2749.l2649&a...
These are reflector style bulbs for a reason.
DO NOT modify the socket distance at all costs. (unless you have a starlight base, which has heat dissipation issues)
The distance to the globe is critical for proper operations
I had a grande that did not put out hardly any light BECAUSE the lava was dense and abundant when cold.
It was also vintage UGLY yellow with Blue fluid
Once the lava flowed and was no longer blocking the light, so it allowed some light to pass through.
Could be a similar issue?
I eventually converted it to Kirk's glitter (large holographic square in blue fluid)
Some colors of lava are nearly opaque, which might be the problem?
I don't think the Frosted v.s.Clear bulbs will change much of the light output
I repair them all the time
I either take the lava and fluid I collected from glitter conversions and swap them out.
For cloudy, I change the fluid,
Or,.. I start new with a Magma Tower goo kit
Check the forums out, there are plenty of topics on repairing them
What is the issue?
Does the lava not flow or is it just cloudy?
Here is example of a goo kit conversion in pic below.
goo need replacement
It sounds like it has separated
Interestingly I have found that the grande r20 frosted bulbs these days can be found in pool spa supply places they are the correct bulb and apparently are used in spas a lot hope this helps for those who don't want to order online.
