Tus nqi sib piv: Upfront vs. Ntev -Tsev nqi ntawm T8 Tubes vs. LEDs

Thaum xaiv ntawm T8 fluorescent raj thiab LED lwm txoj hauv kev rau teeb pom kev zoo, tus nqi feem ntau yog qhov kev txiav txim siab -tab sis tsuas yog tsom rau cov nqi pem hauv ntej tuaj yeem ua rau tsis meej pem. T8 raj tau ntev tau nyiam rau lawv cov nqi pib qis, thaum LEDs nqa tus nqi siab dua ntawm kev yuav khoom. Txawm li cas los xij, qhov tseeb tus nqi ntawm txhua lub tshuab tshwm sim thaum xav txoglong -cov nuj nqis: kev siv hluav taws xob, hloov zaus, txij nkawm, thiab txawm tias tus nqi ib puag ncig. Rau cov lag luam, cov tswv tsev, thiab cov neeg saib xyuas cov chaw, nkag siab txog cov nqi them ua ntej sib npaug li cas rau lub sij hawm ntev - kev txuag nyiaj yog qhov tseem ceeb rau kev txiav txim siab zoo - kev txiav txim siab zoo uas ua raws li cov hom phiaj kev siv nyiaj thiab kev ruaj ntseg. Hauv qab no, peb rhuav tshem qhov ua ntej thiab ntev - cov nqi siv ntawm T8 cov raj thiab LEDs, sib piv tag nrho cov nqi dhau sijhawm, thiab hais txog cov xwm txheej uas ib qho kev xaiv ua tau zoo dua lwm qhov.

Cov nqi them ua ntej:T8 Tubes vs LEDs

Cov nqi them ua ntej xa mus rau thawj qhov peev txheej uas yuav tsum tau yuav thiab teeb tsa lub teeb pom kev zoo - suav nrog cov khoom siv teeb pom kev zoo (tubes / qij), cov khoom tsim nyog (ballasts rau T8s, tsav tsheb rau LEDs), thiab kev teeb tsa ua haujlwm. Nov yog li cas T8 raj thiab LEDs sib piv:

T8 Fluorescent Tubes: qis qis qis qis

T8 raj muaj qhov zoo dua qub hauv cov nqi them ua ntej, ua tsaug rau ntau xyoo ntawm kev tsim khoom loj thiab kev paub tab technology. Ib qho 4-foot T8 fluorescent raj feem ntau raug nqi \\(3–\\)8, nyob ntawm wattage (32W tus qauv vs. 28W qis- zog) thiab hom. Rau ib qho yooj yim T8 fixture (uas tuav 2 raj), tus nqi raj ib leeg yog \\(6–\\)16.

Tshaj li cov hlab ntsha, T8 systems xav tau aballastlos tswj tam sim no -ib qho tseem ceeb uas ntxiv rau cov nqi them ua ntej. Sib nqus ballasts (laus dua, tsis tshua muaj nqi) nqi \\(5–\\)10 ib chav tsev, thaum hluav taws xob ballasts (hnub no, ntau npaum) muaj li ntawm $10– 20. Feem ntau cov tshiab T8 fixtures tuaj nrog hluav taws xob ballasts, tab sis yog hais tias retrofitting ib tug laus fixture (xws li, hloov T12 raj nrog T8s), ib tug ballast upgrade yuav tsum tau. Tsis tas li ntawd, qee qhov qub T8 fixtures xav tau kev sib caispib(ib lub cuab yeej me me kom ignite lub raj), ntxiv \\(2–\\)5 rau ib lub teeb.

Cov nqi txhim kho rau T8 tshuab yog qhov tsawg, tshwj xeeb tshaj yog tias hloov T8 cov raj uas twb muaj lawm hauv cov khoom siv sib xws. Rau qhov project DIY, tsis muaj nqi zog ntxiv. Rau kev teeb tsa kev tshaj lij (feem ntau hauv cov chaw lag luam), cov kws tshaj lij hluav taws xob feem ntau them $ 50- $ 100 rau ib qho kev sib tw-tab sis qhov no feem ntau qis dua yog tias txhim kho ntau chav nyob ib zaug.

Nyob rau hauv tag nrho, tus nqi pem hauv ntej rau 2-tube T8 fixture (tubes + hluav taws xob ballast + yooj yim installation) ranges ntawm \\(30–\\)60rau fixture. Rau qhov chaw lag luam nrog 100 qhov khoom siv, qhov no txhais mus rau kev nqis peev ua ntej ntawm \\(3,000–\\)6,000.

LED Tubes / Qhov muag teev: Kev nqis peev siab dua

LEDs, los ntawm qhov sib txawv, muaj tus nqi siab dua -txawm tias tus nqi tau nqis qis dua kaum xyoo dhau los. Ib qho 4-ko taw LED raj (sib npaug hauv qhov ci rau 32W T8) tus nqi \\(8–\\)15, kwv yees li 2-3 zaug ntau dua li T8 raj. Rau ib tug 2-tube LED fixture, lub raj nqi ib leeg yog \\(16–\\)30.

LED systems tsis xav tau ballasts (uas T8s xav tau) tab sis cia siab rau aLED tsav tsheb-ib feem uas hloov AC fais fab mus rau qhov tsawg -voltage DC fais fab LEDs siv. Feem ntau cov raj LED tau tsim - hauv cov tsav tsheb, tshem tawm qhov xav tau ntawm kev yuav khoom. Txawm li cas los xij, yog tias retrofitting T8 fixture siv LEDs, qee cov qauv yuav tsum tau tshem tawm cov ballast uas twb muaj lawm (tus txheej txheem hu ua "ballast bypass"), uas yuav ntxiv rau kev teeb tsa nyuaj.

Cov nqi teeb tsa rau LEDs me ntsis siab dua rau T8s, tshwj xeeb tshaj yog nyob rau hauv retrofits. Yog tias hloov T8 cov raj nrog LED raj hauv cov khoom siv uas twb muaj lawm, lub ballast bypass tej zaum yuav tsim nyog - ntxiv \\(10–\\)20 rau ib qho kev sib tw hauv kev ua haujlwm (vim cov kws hluav taws xob yuav tsum tau txiav thiab tshem tawm cov qub ballast). Rau cov khoom siv LED tshiab (uas tuaj nrog cov tsav tsheb sib xyaw), cov nqi kev teeb tsa kev tshaj lij \\(60–\\)120 rau ib qho khoom siv -zoo ib yam li T8s tab sis nrog cov khoom siv ntau dua.

Nyob rau hauv tag nrho, tus nqi pem hauv ntej rau 2-tube LED fixture (tubes + tsav tsheb + kev teeb tsa, suav nrog ballast bypass yog tias xav tau) thaj tsam ntawm \\(50–\\)90rau fixture. Rau 100 qhov sib tw, qhov no sib npaug ntawm kev nqis peev ua ntej ntawm \\(5,000–\\)9,000-50–100% siab dua T8s.

Key Upfront Tus Nqi Them Nqi

T8 raj yog pheej yig dua rau kev yuav thiab nruab pib: 100-fixture project nrog T8s tus nqi \\(2,000–\\)3,000 tsawg dua li LEDs. Txawm li cas los xij, qhov sib txawv no nqaim thaum txiav txim siab tias cov khoom siv LED feem ntau tuaj nrog kev lav ntev dua (5-10 xyoo vs. 1-2 xyoos rau T8 fixtures), uas txo qhov kev pheej hmoo ntawm cov nqi hloov thaum ntxov.

Ntev -Cov Nqi Them Nqi:T8 Tubes vs LEDs

Ntev- cov nqi siv sij hawm- suav nrog kev siv hluav taws xob, hloov zaus, kev saib xyuas, thiab pov tseg- yog qhov twg LEDs rub ua ntej. Cov nuj nqis no suav nrog lub neej ntawm lub teeb pom kev zoo (feem ntau 5-10 xyoo) thiab feem ntau tshaj qhov sib txawv ntawm tus nqi pem hauv ntej.

1. Kev siv hluav taws xob: LEDs Txuag 50-70% ntawm hluav taws xob

Cov nqi hluav taws xob yog qhov loj tshaj plaws ntev - cov nqi siv rau lub teeb pom kev zoo, thiab LEDs muaj txiaj ntsig zoo dua li T8 raj. Tus qauv 4-ko taw T8 raj siv32Wntawm lub zog, thaum sib npaug LED raj siv12–18W-txo 44–62% hauv kev siv hluav taws xob.

Txhawm rau kom suav cov nyiaj khaws cia no, cia peb siv qhov tseeb - piv txwv hauv ntiaj teb: lub chaw ua lag luam nrog 100 qhov khoom siv (2 lub raj txhua), khiav 12 teev hauv ib hnub, 260 hnub hauv ib xyoos (ib txwm rau kev lag luam). Qhov nruab nrab US hluav taws xob tus nqi yog $0.15/kWh.

T8 cev: Txhua lub raj 32W siv 32Wh ib teev. Rau 2 lub raj rau ib qho khoom siv × 100 fixtures=200 raj. Kev siv hluav taws xob txhua hnub: 200 raj × 32Wh × 12 teev=76,800Wh=76.8kWh. Kev siv hluav taws xob txhua xyoo: 76.8kWh × 260 hnub=20,048kWh. Tus nqi zog txhua xyoo: 20,048kWh × \\({21}} **\\)3,007**.

LED Tubes: Txhua 15W LED raj (nruab nrab-kev ua haujlwm ntau) siv 15Wh ib teev. Rau 200 raj: 200 × 15Wh × 12 teev=36,000Wh=36kWh txhua hnub. Kev siv hluav taws xob txhua xyoo: 36kWh × 260 hnub=9,360kWh. Tus nqi zog txhua xyoo: 9,360kWh × \\({19}} **\\)1,404**.

Tshaj li 5 xyoos, T8 system raug nqi $ 15,035 hauv lub zog, thaum lub teeb ci LED raug nqi \\) 7,020-kev txuag ntawm \\(8,015**. Tshaj 10 xyoo, qhov sib txawv dav mus rau ** $ 16,030 - ntau tshaj li txaus los them tus nqi sib txawv rau 100 fixtures (\\(2,000-)).

Rau cov neeg siv hauv tsev (xws li, lub chaw nres tsheb nrog 2 T8 fixtures khiav 8 teev txhua hnub), kev txuag me me tab sis tseem ceeb: T8s nqi ~ \\ (56 txhua xyoo hauv lub zog, thaum LEDs nqi ~ $ 25 - txuag \\ (31 ib xyoos, lossis \\) 310 tshaj 10 xyoo.

2. Hloov zaus: LEDs kav ntev dua 3–5 zaug

T8 raj muaj ib txwm lifespan ntawm10,000-20,000 teev, thaum LEDs kawg50,000-100,000 teev-3-5 zaug ntxiv. Qhov no txhais tau tias kev hloov pauv tsawg dua, cov khoom siv qis dua, thiab siv zog tsawg dua rau kev hloov cov raj.

Siv tib lub 100-fixture office piv txwv (12 teev / hnub, 260 hnub / xyoo=3, 120 teev / xyoo):

T8 cev: Thaum 15,000 teev (nruab nrab lifespan), T8 hlab yuav tsum tau hloov txhua ~ 4.8 xyoo. Rau 200 lub raj, txhua tus nqi \\(5, hloov tus nqi ib lub voj voog yog 200 × $5=$1,000. Tshaj 10 xyoo, qhov no yuav tsum tau 2 hloov, tag nrho yog $2,000.

LED Tubes: Ntawm 60,000 teev (nruab nrab lifespan), LED raj xav tau kev hloov txhua ~ 19.2 xyoo - txhais tau tias tsis muaj kev hloov pauv yuav tsum tau nyob rau lub sijhawm 10 xyoo. Tag nrho cov nqi hloov pauv:$0.

Txawm hais tias cov raj LED hloov ib zaug txhua 10 xyoo (rau ultra-ntev- siv cov xwm txheej), tus nqi yog 200 × 12=£ 2,400 - tseem piv rau T8s, tab sis tsis muaj kev hloov pauv ntxiv hauv nruab nrab. Rau qhov chaw ua lag luam, tus nqi zog ntawm kev hloov pauv kuj tseem ntxiv: txhua qhov hloov T8 yuav siv sijhawm 5-10 feeb, tus nqi \\(10–\\)20 rau ib qho kev sib tw. Tshaj 10 xyoo, hloov T8s nyob rau hauv 100 fixtures nqi ntxiv \\(4,000–\\)8,000 nyob rau hauv cov nqi zog LEDs zam.

3. Tus nqi tu: LEDs yuav tsum tau kho tsawg dua

T8 systems muaj cov nqi kho mob ntau dua vim lawv lub neej luv dua thiab cov khoom siv ntxiv (ballasts thiab starters). Sib nqus ballasts (siv nyob rau hauv cov laus T8 fixtures) poob txhua 5,000–10,000 teev (\\(5–\\)10 ib hloov), thaum hluav taws xob ballasts kav 15,000–25,000 teev (\\(10–\\)20 ib hloov). Pib (yog siv) poob txhua 1-2 xyoos (\\(2–\\)5 txhua).

Hauv 100-fixture T8 system nrog hluav taws xob ballasts:

Kev hloov pauv Ballast: ~ 2 rau ib qho kev sib tw tshaj 10 xyoo, raug nqi 100 × 2 × \\(15=**\\)3,000**.

Pib hloov pauv (yog tias tsim nyog): ~ 5 rau ib qho khoom siv ntau tshaj 10 xyoo, raug nqi 100 × 5 × \\(3=**\\)1,500**.

LED systems tsis muaj ballasts lossis starters, thiab lawv cov tsav tsheb (ua rau hauv cov raj) dhau 50,000-100,000 teev - sib piv lub neej ntawm LEDs lawv tus kheej. Qhov no txhais tau tias tsis muaj nqi kho rau cov khoom ntau tshaj 10 xyoo. Txawm hais tias tus tsav tsheb tsis ua haujlwm, feem ntau cov raj LED tuaj nrog 5-10 xyoo lav, them rau cov nqi hloov.

Tag nrho cov nqi txij nkawm tshaj 10 xyoo: T8s=\\(4,500; LEDs=\\)0.

4. Tus nqi pov tseg: LEDs pheej yig dua thiab Eco ntau dua - phooj ywg

T8 fluorescent tubes muaj me me ntawm mercury (5-10 mg rau ib lub raj), cov tshuaj lom neeg uas yuav tsum tau muab pov tseg tshwj xeeb. Hauv Teb Chaws Asmeskas, nws yog qhov txhaum cai pov tseg T8 raj rau hauv cov thoob khib nyiab tsis tu ncua - hloov, lawv yuav tsum tau rov ua dua los ntawm cov ntawv pov thawj, raug nqi \\(0.50–\\)2 ib lub raj. Rau 200 T8 raj hloov dua 10 xyoo, tus nqi pov tseg yog $100-$400.

LEDs tsis muaj mercury thiab tuaj yeem muab pov tseg hauv cov thoob khib nyiab tsis tu ncua (txawm tias kev rov ua dua tshiab tseem pom zoo rau cov khoom siv hluav taws xob). Cov nqi pov tseg rau LEDs tshaj 10 xyoo: **\\(0**. Rau kev lag luam, kev pov tseg tsis raug T8 kuj raug nplua (txog li 7,500 ib qho kev ua txhaum cai hauv Teb Chaws Asmeskas) - qhov teeb meem LEDs tshem tawm.

Tus Nqi Tag Nrho Lub Sijhawm:T8 Tubes vs LEDs

Txhawm rau pom daim duab tag nrho, peb suav covtus nqi tag nrho(upfront + long-term) ntawm 100 fixtures tshaj 10 xyoo rau lub chaw ua lag luam:

Cov naj npawb tau tawm tsam: dhau 10 xyoo, LEDs txuag **\\(20,280** rau 100- kho qhov system-ntau tshaj 48% ntawm T8 system tus nqi tag nrho. Rau cov neeg siv hauv tsev (2 qhov khoom siv ntau dua 10 xyoo), cov nyiaj txuag me dua tab sis tseem muaj txiaj ntsig: T8s tus nqi ~ ving ~ 800 tus nqi tag nrho \\)350.

Cov xwm txheej qhov twg T8 Tubes tseem yuav ua rau muaj kev nkag siab

Thaum LEDs pheej yig dua ntev -lub sij hawm, muaj tsawg zaus uas T8 raj siv tau ntau dua:

Luv -Tsev siv sijhawm: Rau qhov chaw ib ntus (piv txwv li, cov chaw ua haujlwm hauv tsev, pop-cov khw muag khoom) siv rau 1-2 xyoos, kev txuag nyiaj ua ntej ntawm T8s tshaj qhov ntev - txuag hluav taws xob. LEDs yuav tsis muaj sij hawm los them rov qab lawv cov nqi pib dua.

T8 Fixtures nyob rau hauv zoo mob: Yog tias koj twb muaj T8 fixtures nrog cov khoom siv hluav taws xob tshiab (tsawg dua 2 xyoos), hloov cov raj nrog T8s tshiab yog pheej yig dua li kev rov qab mus rau LEDs. Tos kom txog thaum lub ballasts lossis cov raj tsis ua haujlwm ua ntej hloov kho.

Kev txwv nyiaj txiag heev: Rau cov neeg siv uas tsis muaj peev txheej ua ntej (piv txwv li, cov lag luam me tawm tsam nrog cov nyiaj ntsuab), T8s 'tus nqi qis dua yuav tsim nyog - tab sis qhov no los ntawm kev siv nyiaj ntev dua - cov nqi sij hawm.

Yuav ua li cas kom txuag tau nyiaj thaum hloov mus rau LEDs

Yog tias koj txiav txim siab hloov mus rau LEDs, ua raws li cov lus qhia no kom txo tau cov nqi them ua ntej thiab ua kom ntev ntev - txuag nyiaj:

Xaiv Retrofit LED Tubes: Hloov pauv tag nrho cov khoom siv, siv "direct-wire" lossis "ballast-bypass" LED raj uas haum rau hauv T8 qhov (sockets) uas twb muaj lawm. Qhov no txo ​​cov nqi installation los ntawm 30-50%.

Coj kom zoo dua ntawm Rebates: Ntau lub tuam txhab siv hluav taws xob thiab tsoomfwv tau them nyiaj rov qab rau kev hloov kho LED (piv txwv li, \\(5–\\)10 ib qho khoom siv). Tshawb xyuas nrog koj cov nqi hluav taws xob hauv zos kom them cov nqi them ua ntej.

Yuav hauv Bulk: Kev yuav cov raj LED hauv ntau qhov ntau (100+ units) txo ib -unit nqi los ntawm 15–25%.

Xaiv rau Ntev Warranties: Xaiv cov raj LED nrog 10 xyoo lav kom tsis txhob muaj cov nqi hloov pauv.

Xaus

Thaum T8 fluorescent raj muaj cov nqi qis dua,LEDsyog tus nqi ntau dua -zoo rau lub sijhawm ntev-txuag 40–50% ntawm tag nrho cov nqi tshaj 10 xyoo. Kev nqis peev ntau dua hauv LEDs sai sai los ntawm cov nqi hluav taws xob qis dua, hloov pauv tsawg dua, kev saib xyuas tsawg, thiab tsis muaj nqi pov tseg. Rau cov neeg siv feem ntau-txawm yog cov lag luam, cov tswv tsev, lossis cov thawj coj hauv tsev-LEDs yog qhov kev xaiv ntse dua, tsis yog tsuas yog txuag nqi xwb tab sis kuj zoo dua lub teeb pom kev zoo (tsis muaj flicker, siab dua CRI) thiab cov txiaj ntsig ib puag ncig (qis carbon emissions, tsis muaj mercury).

Cov kev zam tsuas yog luv luv -lub sij hawm lossis nyiaj ntsuab- cov haujlwm raug kaw, qhov twg T8s yuav yog ib qho kev daws teeb meem ib ntus. Rau txhua tus neeg, kev ua lej yog qhov tseeb: LEDs yog cov peev txheej zoo dua rau cov teeb pom kev zoo uas kav ntev. Raws li cov nqi LED txuas ntxiv poob thiab cov nqi hluav taws xob nce, qhov sib txawv ntawm T8 thiab LED tag nrho cov nqi tsuas yog nthuav dav - ua tam sim no lub sijhawm zoo tshaj plaws los hloov.
