Pixel voltage is another choice. 5 volt and 12 volt pixels are the most common. Pixel strips usually use 12 volts, but pixel strings
can be 5 volts or 12 volts. Lower voltage pixels tend to be more power efficient, higher voltage pixels can often be made in longer
strings. 50 pixels is a common limit for 5-volt pixel strings. Some 12-volt pixels can have strings as long as 128 pixels.
Pixel controller chip type is another selection to make. You must choose pixels that use a control chip that your pixel controller
supports. The SanDevices controllers are compatible with the following pixel control chips: 2801, 6803, TLS3001, 1804, 1806,
1809, native 1-wire DMX, and the GE ColorEffect pixels (sold at Costco and big-box stores).
Some pixels use 3 wires, some use 4, it just depends on the control chip type. Another important consideration when choosing
pixels is the number of different intensity levels:
8-bits, or 256 dim levels, is the most common (2801, 180x)
5-bits are used for one of the older chips, the 6803. This gives only 32 dimming levels.
4-bits of intensity, or 16 dim levels, is what the GE ColorEffects pixels offer. They are not suitable for slow, gradual dimming.
12-bit dimming is the advantage of the TLS3001 pixels, for 4,096 dimming levels. Although you don't need 4,096 intensity levels,
there are some significant advantages to having 12-bit capability:
Since there is little cost difference between pixel types, we recommend the 12-bit TLS3001 pixels because of the versatility of
the 12-bit dimming range.
