Altura Thermal Management
Most people are not completely aware of how LCD technology works. Believe it or not, LCD's use a bulb to back-light the color-charged liquid crystals. Because of this, cooler isn't particularly better, because in most cases the bulb requires a certain operating temperature to create the brightness necessary for desirable picture quality. But the important factor here is how efficient the bulb is, and what kind of heat byproduct it produces.
The Honeywell MT-HWJCT42B2AB was allowed to operate for fifteen minutes prior to recording temperatures with an Extech 450 IR non-contact thermometer. The room temperature was a cool and constant 22.0°C (71°F) for the duration of the testing period. The collected temperature results are illustrated in the image below:
Most of the heat produced from the Altura MLX came from the top-most bulb vents, which indicate that this unit could be safely placed flat against a wall but adequate ventilation is required overhead. Additionally, the right-hand side of the top panel bulb vent (as viewed from the back) exhausted the most heat, so make sure that surrounding furniture and decorations (such as candles) are not heat-sensitive. The LCD panel indicated a rather low temperature, with only 12°C over ambient.
So what does all of this information mean? How does it effect your decision to purchase the Honeywell Altura? The answers aren't that far away, because I give my full conclusion in the next section.
