Can anyone suggest which decking lights would look better in our garden, those with 2 or 4 leds?
All lamps will have a wattage rating on them and this will give you good clue as to their light output for a given type, but you can’t compare an incandescent lamp rated at 60 W as most of this energy is given off as heat. Better to compare with CFL lamps which are just as efficient as LEDs. A CFL lamp rated at 11W gives out around 900 Lumens, the same as a 60W incandescent lamp. LED lamps typically produce only around 100 Lumens / Watt The LED cluster lamps I have seen are really just for decoration (mood lighting) and provide almost no useable light (not enough to read by for example) Theses LED cluster lamps are rated around 1.2 W which is only just enough to see the egde of a step for instance. There are some on the market which are rated about 5 W which provide a better amount of light but are quite expensive at 6 each.
