El\u0151ny\u00f6k: L\u00e9zerprojektor vs. UHP l\u00e1mpa
Nagyobb \u00fczemid\u0151: A l\u00e9zeres f\u00e9nyforr\u00e1s \u00fczemideje el\u00e9rheti a 30 000 \u00f3r\u00e1t, addig a nagynyom\u00e1s\u00fa izz\u00f3kn\u00e1l be kell \u00e9rni ezzel t\u00f6red\u00e9k\u00e9vel, maximum 5000 \u00f3r\u00e1val. Ez pedig extra k\u00f6lts\u00e9gekkel j\u00e1rhat.
F\u00e9nyer\u0151 roml\u00e1s: Az UHP izz\u00f3k f\u00e9nyereje folyamatosan cs\u00f6kken. A l\u00e9zer\u00e9 pedig csak akkor, ha el\u00e9ri az \u00fczemid\u0151 hat\u00e1r\u00e1t.
Energiafogyaszt\u00e1s: A l\u00e9zer f\u00e9nyforr\u00e1s ugyanakkora f\u00e9nyer\u0151 megteremt\u00e9s\u00e9hez kevesebb energi\u00e1t fogyaszt, mint egy UHP l\u00e1mpa.<\/p>\n\n\n\n

Zajszint: A l\u00e9zer j\u00f3val kev\u00e9sb\u00e9 melegszik. Emiatt azt\u00e1n nincs sz\u00fcks\u00e9g olyan agressz\u00edv h\u0171t\u00e9sre, \u00e9s ebb\u0151l fakad\u00f3an halkabb lehet a m\u0171k\u00f6d\u00e9s.
M\u00e9ret: J\u00f3val kisebb helyet foglal, \u00edgy kompaktabb term\u00e9kek el\u0151\u00e1ll\u00edt\u00e1s\u00e1t teszi lehet\u0151v\u00e9.<\/p>\n\n\n\n

El\u0151ny\u00f6k: L\u00e9zerprojektor vs. LED
F\u00e9nyer\u0151: A l\u00e9zeres f\u00e9nyforr\u00e1s j\u00f3val nagyobb f\u00e9nyer\u0151 el\u0151\u00e1ll\u00edt\u00e1s\u00e1ra k\u00e9pes, mint a hagyom\u00e1nyos f\u00e9nykibocs\u00e1t\u00f3 di\u00f3d\u00e1k. Ez\u00e1ltal a k\u00e9p min\u0151s\u00e9ge jobb lesz!<\/p>\n\n\n\n

H\u00e1tr\u00e1nyok: L\u00e9zerprojektor vs. LED & UHP
A l\u00e9zer technol\u00f3gi\u00e1a teh\u00e1t technikai param\u00e9terek tekintet\u00e9ben jobb, mint a riv\u00e1lis megold\u00e1sok. Azonban van egy h\u00e1tr\u00e1nya: ez pedig az \u00e1r.
