Hooga Amber Book Light, Blue Light Blocking Rechargeable Dual Mode Night Reading 1600K Amber and Red 625nm for Reading in Bed Gift for Students, Kids

It's not super bright, and it may be not a great fit for an e-book of A4 format, or an e-book with a very glossy surface. I'm using it with my Remarkable to read books, and I'm very happy. I'm sure it'll work well with the normal sized books as well. It allows to cycle between yellow-redish light, white light, and in-between (the one I use the most). I'm using it about 4 hours every evening – and I battery holds well.

This is simply a brilliant reading light. It's very adjustable with brightness and various angles. It's very clever in that it doesn't use any of the blue light frequency that disturbs your sleep process. Just one thing to add, maybe it could be more travel friendly if it folded up for more protection. However this light is simply great. Stop looking and get this one.

This is such a great book light. Has bright white and a dimmer warm light. Clips on well, stays put, holds a charge for a long time. My kids use these daily and they have held up very well over several years. Great function and quality at an affordable price. We have 4 of them and none have broken and they still hold a charge after 3 years.

En verdad la recomiendo mucho. Buen tamaño, resistente, buen grip, iluminación suficiente para leer por las noches.

¿LUZ DE LECTURA? Imposible. La medición a sólo 10 cm del foco de luz es de 220 lux a máxima potencia en la luz roja, parece una broma. Lo mínimo para no producir cansancio ni daño ocular son 500 lux. Las dos opciones de luz ámbar son algo más potentes, pero para mis ojos chillonas y molestas. No es el ámbar que imita a luz de vela que esperaba. Si lo que buscas es una luz pequeñita, muy pequeñita en realidad, para encenderla por las noches si te tienes que levantar y no desvelarte, creo que funcionará muy bien. Además, la pinza es potente y parece robusta. A pesar de que el anuncio especifica claramente que es una luz de lectura cuando no es el caso, para devolverla, me encuentro con la sorpresa que ya empieza a ser habitualde que tengo que pagar yo los gastos de envío y mandarla a otro país. Comparada con una luz equivalente comprada aquí en Amazon de “marca blanca” no veo diferencias que justifiquen pagar casi cuatro veces más. Quería que me gustara porque me gusta esta marca y soy muy fan de la terapia de luz roja, pero no ha podido ser.

I use it for low light observations and photography with my telescope. It clamps easily on my tripod. Isn’t larger or cumbersome nor heavy at all and holds really well. Doesn’t move around and isn’t in the way or a problem at all. The amber light is a bit bright but doesn’t affect my night vision much. It’s good when I accidentally drop anything and record things in the log book. The red light is awesome. Very low light and I can keep it on during observation without disturbing the darkness. The amber/red combo light is good for quick logs and changing eyepieces. I’ve charged this once since I’ve got it. Haven’t needed to charge it since. Still holding holding charge well. Overall, whether for astronomy, astrophotography, reading and writing it’s well worth the investment.
