Los ntawm txoj kev pom, qhov tseem ceeb ntawm cov teeb pom kev zoo ntawm LED yog nyob rau hauv lawv cov luminous efficiency. Thaum ib txwm muaj siab - cov teeb hluav taws xob sodium muaj qhov ua tau zoo ntawm kwv yees li 100 lm / W, LED txoj kev muaj peev xwm ua tiav 150-200 lm / W, ua rau 30% -50% txo qis hauv kev siv zog rau tib theem ntawm qhov ci.
Tsis tas li ntawd, LED cov teeb pom kev zoo khav theeb lub neej ntawm 50,000 txog 80,000 teev-tsib mus rau kaum npaug ntawm cov teeb sodium- yog li txo qis cov nqi kho mob. Nyob rau hauv cov nqe lus ntawm kev tsim kho, siab - zoo LED txoj kev teeb feem ntau feature lub cev ua los ntawm galvanized steel los yog aluminium alloy ua ke nrog polycarbonate (PC) npog; Qhov kev tsim qauv no ua kom muaj kev ntsuam xyuas IP65 rau dej thiab plua plav, ua haujlwm txhim khu kev qha hauv qhov chaw huab cua xws li -40℃txog 60 degree.
