求翻译：一般来说，在同一瓦数之下，一盏节能灯比白炽灯节能80%，平均寿命延长8倍，热辐射仅20%。非严格的情况下，一盏5瓦的节能灯光照可视为等于25瓦的白炽灯，7瓦的节能灯光照约等于40瓦的，9瓦的约等于60瓦的。是什么意思？

In general, under the same wattage, an energy-saving lamps than incandescent energy saving 80%, average life expectancy of eight times, the thermal radiation of only 20%. Non-strict case, a 5-watt energy-saving light photos can be deemed to be equal to 25 watt incandescent bulb, 7 watt energy-saving

In general, at the same wattage, under an energy saving lamp energy than an incandescent 80% longer life expectancies, 8 times, only 20% radiant heat. Non-strict, a 5-watt energy efficient lighting snapshot can be regarded as equal to 25 Watts of incandescent lamps, 7 watt of energy-saving lamp 40W

Generally speaking, under the identical wattage, an energy conservation lamp conserves energy 80% compared to the incandescent lamp, the mean lifetime lengthens 8 times, the heat radiation only 20%.In the non-strict situation, 5 tile energy conservation light according to may regard as was equal to

In General, under the same wattage, a energy saving lamp 80% energy than incandescent lamps, and average life expectancy to extend 8 times times, thermal radiation is only 20%. Non-strict case, a 5-Watt energy-saving lamp illumination can be considered equal to 25 watt incandescent lamp, 7 watts of
