I've purchased several Leptoech light units similar to these and been very happy with these purchases. These particular lights are the favourite I have purchased so far. A nice surprise was the ability to change the colour temperature of the LED's from COOL WHITE to NEUTRAL WHITE to WARM WHITE. I did not realise this was a feature of these lights when I purchased. I purchased them for a COOL WHITE application, but now that I know they are variable, I will order some more for some other tasks where the option to change will be nice. Like my other Lepotech lights, these are very well made with sturdy metal bodies that are nicely magnetic against ferrous surfaces.
