I have these spotlights in outdoor use to illuminate a tree, which (with only 2 (!!!) watt) quite outstanding works in conjunction with a wide-angle LED bulbs. At first I was a bit skeptical because of the original purchase price promised a high quality and precisely manufactured radiators, but only an average manufactured product offers. The fittings are made of, for example, cheapest (badly galvanized) materials that I've replaced by stainless steel fittings. Finally, I must at some point the radiator open to switch the light source, which has not facilitated by rusted screws with security ..... However, the cheap nuts and bolts are the only shortcoming, why only 4 stars. To be fair, it should be noted that I bought the spotlight as a flash offer on cybermonday - and since then the price / performance ratio.
PS in the "detailed" description an error has crept. It says: "Only for use in enclosed spaces". For a garden spotlight somewhat impractical ;-) there should be improved.
