Use it in your living room, bedroom, bathroom or any space you feel like and enjoy the pleasance of ocean waves indoors. The Ocean Waves Projector Lamp & Speaker is a simple design but the way it projects natural beauty on the ceiling makes it one of its kind. This is because it is a projector lamp which reproduces the charming effect of the sparkling sea at home. You’ll be able to feel the calm essence of the ocean waves and enjoy peace and natural beauty as and when you wish to. The fact that it’s also a small stereo speaker makes the whole thing even more adorable. The device will use 4 AA batteries but can also support external USB and 4.5V DC plug. Not only this, you’ll also get to conserve energy with the automatic sleep function that will close the projector by itself after one hour of constant use.
