<DIV><BR><FONT face=Arial size=2>The new XLamp XP-E2 LEDs from Cree are claimed 
to deliver more lumens per watt and lumens per dollar to lower system costs for 
existing XP-E and XP-G designs. The new LEDs can increase the light output of 
existing XP-E designs at the same cost and power or reduce the system cost with 
fewer LEDs, enabling lighting manufacturers to deliver&nbsp; better lighting 
systems with minimal redesign.</FONT></DIV>

<DIV><FONT face=Arial size=2>The LEDs have the standard XP footprint (3.45 x 
3.45 mm) and are optically compatible with all XP LED versions, including the 
popular XP-E and XP-G. The LEDs generate cool white light (6000 K) at up to 
<STRONG>128 lm/W at 350 mA and 85 °C</STRONG> or <STRONG>143 lm/W at 350 mA and 
25 °C</STRONG> and are suitable for a broad spectrum of high-lumen applications 
for indoor and outdoor lighting, portable lighting and lamp retrofits 
and.</FONT></DIV>

rašė:<BR>&gt;&gt; Kvaily. Klausei led'u su srautu &gt;100lm/W, gavai. Ko dar 
knysle sukioji?<BR>&gt;&gt; FL'ai siltu spalvu beje irgi ne tiek efektyvus kaip 
saltu<BR>&gt; <BR>&gt; Avine, klausiau lempučių. Nes lubose šviečia ir liumenus 
į plikę siunčia <BR>&gt; ne pliki, 25°C temperatūros led'ai, be maitinimo ir 
optikos nuostolių, o <BR>&gt; *lemputės*. Ir ne gatvinio apšvietimo 
prožektoriai.<BR>&gt; Todėl, kai naivuoliai lygina ir daro išvadas, kaip kas 
šviečia jų <BR>&gt; butuose (led vs halogen; operuojama idiotiškais dzian-liao 
liumenais iš <BR>&gt; jebejaus ir priešpastatoma tai tikriesiems halogenų 
liumenams), o tokie <BR>&gt; avinai, kaip pats prisijungia pasapalioti, kad 
led'ai šviečia virš 100 <BR>&gt; lm, tenka kantriai (kiek tai įmanoma) aiškinti, 
kur tie liumenai <BR>&gt; žiemoja. Ir mitus bei iliuzijas 
sklaidyti.</FONT></BODY></HTML>
