very bright the only problem is that the bulb compartment falls offfrom the battery compartment too easily.

This light makes sense in one aspect; it has two lights - one for each page.  I really like this design, but that is where the love ends.  The light "clips" to the book by wedging the thin strip of plastic between the book pages and spine.  This is dumb for two reasons.  One it is rough on the book and pages, but moreover it makes the batteries fall out because of a serious design flaw.  The bottom part of the light is supposed to clip together to hold batteries in, but it comes apart constantly!!  If this light had a better clip on it that didn't damage the book and would actually stay together in one piece, then it would be a good light.  As it is, it is just a a real pain.

I needed a LED with this somewhat rare combination of voltage and form factor to replace a halogen bulb used in a bedside fitting, as the latter would get dangerously hot. This bulb does do the job, giving off a nice, warm, bright glow. However, it is not especially well built. Apart form the sides seemingly being made of plastic, not metal, the bipin connector was loose, sinking inside the bulb body when I tried to stick it in a socket. I had to pull it back into place with some pliers, then very carefully insert it into the socket to avoid loosening it again. All in all I'm satisfied though. (The energy savings don't hurt either).

The bulb's okay, it's the light fixture itself that's cheap and poor quality parts

When the slider rail is attached, the battery compartment opening is useless, because the locking latch for the slider attachment is in the way of removing the battery.  This means removing the camera from the cage instead of leaving it mounted inside, which means adding an easy release inside the cage which reduces stability, especially with the follow focus.

Adding an easy release inside the cage is further necessitated by the fact that by the time the rails and a tripod mount are added, the camera mount screw is inaccessible from the outside, unless you want to dismantle the entire assembly every time you need to change a battery.

The construction is decent and solid but these design flaws definitely hamper enjoyment.

Works well for a little while; light bulb went out so quickly it is too expensive to keep replacing that quickly.

It seems the bulb easily goes out if anything happens... even a slight move sometimes, but other than that, it's cheap, love the size, and the beardie digs it.

Good LED but the battery keeps falling off. I cannot use it for a min without the battery falling off.

The light is inexpensive and did well to give light, but the big knob and the cover around the bulb fell off immediately and wouldn't stay attached to the light. It still worked since there is a smaller on/off knob under the large one and you don't need the cover for the light to work. Bottom line - the clip and the light both work which is all I needed, it just looks terrible because all the other elements fell off.

Battery compartment is not easy to get to. I have purchased two and both have quit working almost immediately.

1. The bulbs inside are not centered and there is leakage from one compartment to another making it hard to identify what exactly is lit  when you are not standing directly in front of it.

2. Build quality is very poor.

I returned mine.

Very difficult to open battery compartment without breaking but once the batteries are in the lights are nice.

The battery falls out the battery casing easily. I use this flash on a regular basis and now I'm using good old duct tape to hold the battery compartment together.

This little light is incredibly bright! But... The box that the light came inside of, other parts and pieces, had loose batteries flying around during shipping. And it shattered the glass of the light. That seems like an easy fix? Secure the batteries somewhere ? Maybe? Anyway, the light worked kind of ? But it kept flickering off and stuff so we became concerned after it wasn't working very well.

Very bright but don't bump into it or hit the head.  The bulb inside is very loose and not a strong connection.  They should replace it with a better connection type bulb besides a basic push in type.

Battery compartment loses lid due to tiny latch extrusion immediately breaking off and I can't keep the battery compartment closed.

These lights seem good at first. The remote is great offering many color choices. However the bulb itself falls apart extremely easy. I Got mine a while ago but did not use until recent I had placed it in one location but that did not work out, so I went to change the location and when unscrewing the bulb it separated from the threaded part, the led lights in one section and the threaded part in another. This happened on both bulbs only used 2 times. So just be aware of this when screwing and unscrewing the bulb in. Other than that they are good bulbs, but the fact they separated into two pieces makes them unusable and therefore not worth the money.
