For the price a real bargain

(+) Quality workmanship (aluminum)
(+) Good light output. Illumination and beam range are amazing for the little lamp
(+) Burn time: good.
(+) Well functioning on / off switch (at the rear of the lamp)
(+) Portable - can easily be transported in trouser and jacket pockets
(+) Practical metal clip
(+) Can be easily focused by the illumination ring on the lamp head
(+) No frills
(+) Price / performance ratio: Very good

We use a bulb predominantly in executing our dog.
I would buy the lamp again.
