The light output is measured just in this center area.

At night when the light output is reduced, it uses only 3W of power.

Both systems offer superior light output with low energy requirements.

Light output in the first few minutes drops at low temperatures.

The light output was also stable to better than +/-2% over the measurement period.

The emphasis is on accurate control over the levels and direction of light output.

But this is not the case, particularly if you are using a modern high light output projector.

They require a warm-up period of several minutes to reach full light output.

In the early days, as the technology was developing, there were issues with warm-up times, general light output and their size.

Only two of those actually failed, the others I replaced because the light output and quality had decreased.

Lamps will actually shut off when the light output is no longer truly effective.

A two stage light output means you can reduce fan noise and save on power.

The light output is quite low, however, and very sensitive to variations in temperature.

That makes the glass appear darker and reduces the light output.

It allows for particularly small headlamps with high light output.

It gives a more uniform presentation of the light output in operation.

They are not very energy efficient, and the light output tends to decrease over time.

The light output from the viewboxes should be uniform to within 10 percent.

Dirt and dust accumulation can reduce light output by 30%.

Electrostatic focus, similar to the 6" & 7" but with an increased picture area for added light output.

These units can deliver a similar light output with reduced power consumption.

However, next to light output and efficiency, these characteristics are footnotes.

This model has no low mode for light output.

Their low light output means that the habitable zone is far closer in.

Compact with high light output and low heat loss.
