On the Q2, the 300 lumias seems low compared to some that have 3000. Is it the same because of led?

300 is only for dark areas such as basement use. with a screen sides about 6 feet wide viewing or screen demension of 90 inch projection. 3000 will alow you to see in the day time with light interference. Ideally 1200 lumias would be a good output I have used my Qumi Q2 for a total of 11000 hrs on high and 757 hours on eco mode as of today use. It is a great portable projector. I have a few gripes about it when it first came out. you may look at my previous comments and reviews. any more question just ask. again this was the first generation model. I use this with my ps3 or computer. Its an impressive little thing.. Yes 300 is very low.. meaning you have to move it closer to the target area and you will have a smaller veiwing space if there is high level of ambient light around

300 lumens in any projector will be less bright than 3000 lumens in any other projector. But important also is the contrast ratio. A high lumen projector with a low contrast ratio will show fewer shades of color than a lower lumen projector with a high contrast ratio. To get the most benefit of the Q2's 300 lumens, be sure the room is dark. Then your eyes will become more sensitive to the light on the screen in time.

i ordered the 600 but when i called to complain about something, they told me that i was supposed to get the 420 but they, for some reason, decided to upgrade me to 600. i guess it was their way making it sound like i was getting more than i paid for. also, watch out for the number of LED lights (for night vision). if you place an order, remember what it was for so that, if you call to complain, you have the right info.

Also keep in mind that battery life is shorter the higher the brightness setting.

Idk if there is a brighter color. I got the 8k and am very happy with the light blue look. They are very very bright. I think the colors only change and brightness is more then likely the same. I would suggest 6k 8k or 10k in my opinion.

I also bought a refurb and love it. I went into the settings and turned brightness way down but its still seems plenty bright. You can check in settings and see which programs are the biggest drain. Turning off Bluetooth will also help. I think companies always overestimate how much battery life they can achieve (they probably measure the life by how long you can listen to mp3's continuously). I don't think you should be concerned.

I cannot compare as I do not own both. But I do have the View Sonic and the LG, and both displays have excellent color accuracy when delivered and used on the DVI port using native resolution. The big rub is that the as delivered brightness is so high as to cause significant eye strain if used more than 1 1/2 hours. If you reduce the brightness, you will not get the advertised Dynamic Contrast Ratio. In addition the as delivered brightness causes a non acceptable light bleed around 1 or more edges. All of the above are to be expected on these LED backlit, IPS, WQHD displays, and getting one acceptable to you is a matter of luck and original engineering design tradeoffs. These displays are at least 2 or 3 times better than the old 1920 x 1080 displays. Good Luck.

While I have not specifically timed battery life under high or low settings, my observations are that on the high setting, the light lasts on the order of several hours but the brightness decreases fairly early on. The light still provides useable light when the brightness wanes but do not expect the light to be "300 lumens" for more than an hour or two. I do not use the light on the low setting.

I purchased both the XL100 and the XL50 in Jan 2011 and the light on the XL100 is not as bright and has a slight yellowish tint compared to theXL50. I am suprised as I thought the only difference was going to be theextra features of the XL100.

Lumins don't seem to mean much as far as brightness. I finally went by colortemp. Higher the temp the brighter. I just used a dimmer.

I'd say possibly one of three things - 1. Your 'brightness' setting was turned down during the install (which you can fix in the control panel by swiping up from the bottom of your screen in ios7) 2. That there is an issue with the quality of the screen (which isn't fixable, you should have them send you a new screen at their cost as it is a manufacturing defect) 3. The backlight shorted out/isn't working (might be your fault if you weren't careful during the install, but also might be a manufacturing defect with the screen... but it's hard to say which without seeing the phone) Hope that helps

Dear Friend.. My first suggestion is not to buy Nokia Lumia 720. This phone doesn't support most of the top apps available in market today, problem is it not even support the apps which supported by other Nokia Lumia phones. Till now it didnt got windows 8.1 update where as the other lower end phones got updated.

Do the st50 series seem brighter than the st30? That has been my main complaint so far of the st30 at the stores. I know the lighting will not allow a plasma to shine in a store atmosphere, but a little more brightness would be nice.

from what ive heard the speakers have been downgraded from the 1000h, the battery life has also been downgraded., the screen brightness downgraded, ummmmm makes me wonder why they even changed over, i guess the only benefit to the new 1002ha is pure aesthetics. dont make sense to me, i'm gunna get the 1000 instead.

Supposedly. I adjusted it as brightly as possible, but it is still way too dim. Other than that, I like the phone.

Power draw depends on the power settings. As I have turn down the settings when on battery mode to LOW, I get 7-8 hours. This is achieved when my display settings is only 35% brightness. Which is fine with me.What I do not like about the battery is there is already a 6% capacity wear the day I received it. So from day one, my capacity is only 94% of capacity. One other thing, the upgrade to win 8.1 Update 1 is complicated and error prone using MS files. Better use a ISO with upgrade already built in. Mine is now Entreprise 8.1 Update 1 after some difficulties. Remmember to load drivers in certain order or your MSATA cache will not work. Power draw depends on the power settings.

I tested three Lumias, a 920, 1520, and 950 individually with no other devices charging. For the 1520 it delivered 1.5 amps on any port. For the 920 it delivered 1.3 amps when connected to either of the top ports (Power IQ ports) and 1.1 amps from any of the other ports. It only delivered 1.0 amp from any port to the 950.

I loved this phone. Only issue for me is call quality is a little tinny sounding. If you can live with that go for it because everything else including photos (big deal for me) is great! Don't know about LED notification.
