I've used lots of different types of microscope lights professionally, but never an LED one until now.
First impression was how light and 'plasticy' it felt. Plugged it in for a test before fitting it to the microscope, a Bausch & Lomb SX4 with the 0.5X objective, to make sure it worked. Plugged it in, turned it on, looked to see how bright it would get and mistake. Don't look directly into it. No pain or damage, but it is pretty bright. Dims to fairly low. Time to try it out!
Put it on a ring light adapter we already had. The enclosed adapter WILL NOT fit this microscope since it has a 1.5" x 1/32" thread (from memory check your manual to be sure). I knew it wouldn't from the description and counted on the opening to be about right. The ring itself is a close fit to the adapter I had already. It feels like it will help stabilize the light in addition to the three screwed in holder. There are no 'rubber feet' on the screw ends to help them grab, so I'll see how it holds over time. Worse comes to worse, it would probably stay on with a rubber band wrapped around the adapter. It's that close a fit to the adapter.
The light from it is toward the bright end of what I'd like for a light. For a good amount of light for my work it's adjusted toward the dimmer end. That speaks well for it's potential longevity since the brighter and longer LEDs operate, the quicker they dim. They say in the description it's a 'cool' light, and it is. Much bluer a tint than my old fluorescent ring light. The light seems well distributed and I didn't notice any spotty reflections from all the individual LEDs like I expected I would. With the 0.5X objective the viewing distance is about 6", so if your microscope has a different range this observation may not apply.
I'll have to use it more to be sure, but for my purpose, examining electronic circuit boards, I think it'll be fine.
