I had several of the original MightyBright 2-headed LED lamps, and was quite happy with them, and wrote a favorable review for Amazon. When I learned about the new version, which had two LEDs per head, more options to select the amount of light, and the option to use an AC adaptor instead of batteries, I bought a set of the new ones.
The build quality seems slightly better than with the older version (my only real complaint with the originals). Otherwise the battery/clip base and flexible goosenecks seem to be the same as with the originals. The heads are where the difference is most apparent. The lens over the LEDs seems to distribute the light more smoothly over the music page, and the switch on the head allows three choices: OFF, 1 LED on, 2 LEDs on. Obviously, 2 LEDS on is brighter than 1 LED on, but it will also result in decreased battery life. Happily, this new model comes with an AC adapter that plugs into the battery base. A concern: accordingly to MightBright, you cannot use the AC adapter while the batteries are installed in the base. Apparently, there is no isolation circuitry between the Ac adapter's plug and the batteries, so the AC adapter is trying to charge the batteries, and they will get hot or otherwise cause problems. I wish MightBright had incorporated an isolation circuit to disconnect the batteries when the AC adapter is plugged in, but this would be my quibble for this model.
On a more disturbing note, my initial order with Amazon was for three of these, and on two of the three units only one of the two LED heads would turn on. This appeared to be due to faulty switches on the heads. I returned those two faulty units for refund, and ordered two replacements. The new ones worked correctly. I hope that the ratio of good to bad switches is high on units that other people may buy!

I have trouble seeing my music when I'm playing violin in a room that's not well lit, and this light makes a big difference -BUT instead of having a slide switch like the previous light (which has only 1 light/head, not enough), this version has a press-the-button-to-turn-on switch on the back of each head. Moreover, the switch sticks out, so it's next to impossible not to have it turn on accidentally while it's curled up in your instrument case. Then the next time you pull it out, desperately needing it, no light! Dead batteries. Bummer. There's no way I can figure out how to carry this supposedly portable light around without accidentally having it click itself on and run down the batteries. Maybe you just have to take out the batteries before you pack it up, which is really lame, and I can't imagine how the Mighty Bright people traded in a good slide switch for a cruddy, exposed, stick-out, button.Good light, but useless if there's no juice left in the battery.
