Advantages: Huge. Soothing. Good value. Disadvantages: Takes forever to heat up.
A lava lamp is, in principle, very simple. It consists of a lamp, which heats up a glass bulb filled with a waxy solid and a liquid. These cannot mix together and must have very similar densities. As the solid heats up, its density is lowered, so it rises. This cools it down and it then falls to the bottom of the lamp, creating a strangely soothing effect. In practice, making one yourself would involve messing about with expensive and perhaps flammable chemicals, so I wouldn't bother trying. It is much easier just to buy one yourself.
The Giant Grande Lava Lamp comes in two colours yellow and blue or yellow and violet. It is truly enormous at 27" and is guaranteed to be a focal point in your room. It is not called "giant" and "grande" for nothing!
My lamp is a yellow and blue model. Although the product description says "yellow ...
Advantages: Portable, quick to turn on/off, very easy to set up and use. Disadvantages: Loud cooling system, rubbish internal speaker.
three devices can be connected. Switching via signal sources is very simple, remote control has three default buttons (computer, video, composite), each one for different device display.
Focus is manually adjustable next to lens. It has vertical keystone (+-30; must have in modern projectors) and display can be electronically shifted off centre up, down, left or right (about 10% of it's width/height).
Projector has build in mono speaker (audio signal input by double audio line-in), but not loud (only 1 Watt) so it's usage is limited.
Bulb life cycle is 2000h in normal mode (does anyone use economic mode at all?) which is standard in that price range. Replacement bulb is about £120, and is dead easy to fit in.
Epson give 3 years warranty for S3 body and 90 days for lamp. In my opinion, it's fair deal.
Now my experience with that product ...
