GOLOZA LA-C337-Red Projection Alarm Clock with 180° Projector and Red LED

For anyone who wants to check the time from bed without relying on a small bedside display, the GOLOZA LA-C337-Red projects the clock face onto a wall or ceiling. Its projector arm rotates 180° for positioning, and the red LED display has three brightness levels. One important outage detail: the backup button battery saves the time and alarm settings, but the display turns off and the alarm will not sound while power is out.

Best use cases

This clock is designed for a bedroom setup where seeing the time at a glance matters. The projection can be placed on a wall or ceiling from a stated distance of 0.5–3 m, making it an alternative to a standard bedside clock that can only be read by looking at its face. The red digits are also visible on the curved display, so the projection is an added way to check the time rather than the only one.

It suits you if you want a clock with an adjustable projection and an alarm whose buzzer volume rises progressively. The large snooze button adds a simple way to delay the alarm for 9 minutes. It can also be used on a tabletop in other indoor rooms, though the projection is most relevant where you can see the wall or ceiling from your usual position.

Why it’s worth it

The main appeal is having two ways to read the time: a red display on the clock and a projection that can be aimed toward the ceiling or a wall. Separate brightness adjustment for the display and projection lets you set each to one of three levels, useful when you want to keep the room darker at night without giving up a visible time display. The USB output can also charge a phone or another device while the clock is plugged in.

Buyers commonly praise the legibility, adjustable brightness, projection, and straightforward setup. Those comments support its appeal as an easy-to-use bedroom clock, but they do not change the practical power limitation: during an outage, the backup battery preserves settings only. The clock does not show the time or sound its alarm until power returns. Better avoided if you need an alarm that keeps operating through a power failure.

Practical questions

Can the projected time be aimed at the ceiling? Yes. The projector arm rotates 180°, and the listed projection distance is 0.5–3 m.

Can the display and projection brightness be adjusted separately? Yes. Each has three brightness levels, according to the product details.

What happens if the power goes out? The built-in CR2032 battery saves the time and alarm settings. The display stays off, and the alarm will not sound during the outage.

Is it worth it?

Choose this model if projection is a feature you will actually use and you want a red LED clock with adjustable brightness, progressive alarm volume, and a snooze button. Compared with a basic clock that shows the time only on its face, its rotating projector offers a more flexible way to view the time from bed. If you only need a conventional bedside display, that extra projection function may not be a deciding benefit.
