I did not invest in the same thing by Manfrotto as it is to light in uncertain underground and be transported in caving bags. Broadcasters filters do not take up, construction is light, not too strong to say everything. It should also remove the batteries after use because it is not like a Maglite ... they will discharge itself if left in place. Lighting is homogeneous, the uncertain color temperature but at this price you do not grumble. This lamp perfectly fulfills the function for which I had intended, and I will not have to put it to the dump as with other rechargeable LED lamps with the integrated battery is impossible to change (while the LEDs are still functioning perfectly). The day she will fall and it will be broken, it will certainly make me less harm to finance that if that happened with super-pro equipment that does not light better (I could compare)
