Optoma HD20 DLP Projector Review
There's plenty to be excited about in the Optoma HD20. It's a 1080p projector for under a thousand dollars.
The Optoma HD20 is not particularly loud. In a room with an ambient noise level of about 37 decibels, the projector added about 5 decibels with the lamp in Normal mode. If we bump the lamp up to Bright mode, the noise increased by 7 decibels.
The Optoma HD20 can get quite warm. In a room with an ambient temperature of 78 degrees (F), the exhaust fan was kicking out a peak of 119 degrees (F) when in Normal lamp mode. If we switched the lamp to Bright mode and let it run for about five minutes, the exhaust fan's temperature increased to 129 degrees (K). Practically speaking, this means that you should not plan on sitting friends or family members next to the projector while its running. If you're in a classroom, feel free to put students next to it. Kids are tough. They can take it.
The Optoma HD20 uses various amounts of power depending on the user mode and lamp mode. The details are all in the table and chart below. In total, it costs about $49 per year in Normal lamp mode and $59 per year in Bright lamp mode.
The Optoma HD20 uses the Optoma BL-FP230D bubp, which is rated for approximately 3000 / 4000 hours in normal / bright modes. Understandably, we don't test this number as we don't have 125 / 166 days to run a test. Hopefully, Optoma is close to honest on this one.
