I checked that horrible Youtube video from Optoma in which the company apparently try its best to show the pj in its worst environment, but at least we got to see several shots of the rear of the unit and, surprise, surprise, instead of a DC Pin to connect to an external power supply like every other pico/mini pj i've seen, the Optoma ML500 has a detachable AC power cord input with the power transformer placed inside the unit !
Considering that the ML500 is rated at 500 lumens and yet uses the same "HD Pico" DMD chip from Texas Instruments in conjunction with a LED chipset from Luminus Devices, how is it capable of having twice the brightness of the LG HW300T and the Vivitek Qumi, both of which use the same "combo" ?
Apparently, Luminus Devices introduced a new LED chipset model last year, SBT-16, which was designed specifically to be used with pico/mini/micro projectors; It is optimized for micro displays ranging from 0.2 to 0.4 inches diagonal and yet, as far as i could find out, the new "HD Pico" DMD micro display chip from TI measures 0.55 diagonal...
Luminus Devices also has more powerful LED chipsets like the model PT-120 which have been used in the xxx-expensive LED pjs selling for over $10.000, and yet the company sells them to anyone for only $210 (the complete R/G/B LEDs set !?), so i wonder if Optoma is using the PT-120 chipset in the ML500 instead of the lower-spec'd SBT-16 to achieve such high brightness level of 500 lumens, considering the larger size of its case, the use of a detachable AC power cord and rated power consumption of 120 watts max.
To my inquisitive eyes, it's either that or the Optoma ML500 uses the same "combo" as the LG and Vivitek units, in which case the company is being widely optimistic in its assumption of 500 lumens of onscreen brightness or the other two companies are being too conservative in their own estimates, which i doubt very much; And keep in mind that Optoma has also announced the ML300 LED pj, which is rated at 300 lumens and appears to have the usual DC IN pin for an external power supply, not an AC power cord.
I was also surprised and amused by the number and types of I/O : HDMI, USB, mini USB, VGA, SD card slot, composite AND S-Video (!?)...
Hmm, things are getting "curiouser and curiouser"....
" so i wonder if Optoma is using the PT-120 chipset in the ML500 instead of the lower-spec'd SBT-16 to achieve such high brightness level of 500 lumens, considering the larger size of its case, the use of a detachable AC power cord and rated power consumption of 120 watts max. "
Isn't that what the Pico LED light source was all about ? lower cost in power consumption ? for example, some boasted that the power consumption would be under 100 watts.
So what's going on here ? 120 Watts ?
Maybe they are moving things up the latter and moving us into the next generation of Pico - general use projectors with more power ?
I am going out on a limb here and say that they are using the PT-120 because of the 120 Watt rating.
MCaugusto ? I don't know if and when you may buy one of the new 500 Lumens projectors, but ? if you do ? can you or will you compare it to your impressions of the state of the art for example when you got the LG's models and I know it's not a fair comparison however, what's your impression of it's brightness, resolution, over all wow factor of one of these clone 500 Lumens projectors.
By the way ? what company in most people's minds would have the best quality.
I still have a old Infocus X-2 that still works and only has 300 hours on the bulb and the LG-HX-300.
The LG HX-300 plays movies fine, but, I felt like I got buyer's remorse after getting it, and it only has about 150 hours or less on it.
