can you see a difference between the 660 and 630 nm colors, I bought one of these and can only see one color led. any help would be appreciated.

There is very little difference in the spectrum between 660 and 630 nm so you will not be able to notice a color difference. We're very happy with these lights!

I bought a variety of them new and used, never noticed a difference in growing.. Ive only got one that looks all red the others look kind of pink and red

I cannot discern a difference in either of mine so I'm sure yours is fine. It may not be a visible difference to our eye, I am fairly confident the G8LED stuff is/does exactly what it says.

It's only supposed to be red; And is meant to be used during the flowering stage... My flowers have almost doubled in size since I started using it

Dear Mstruyf , Nice day. Thanks for your interest on this item. This is Lydia from customer service team, it's my pleasure to help you. So you mean the size or the watt of the LED? If for the watt of the LED, 250W or 400W is much better. Thanks for your time and best regards! Lydia

I believe the 650 is 12bit color processing and the 750 is 16bit color processing as well. Lately the 750 is CHEAPER than the 650 currently on here by about $25, but when I got my 750 at hhgregg last week it was $300 cheaper than the 650 O_o

Thanks Pat, In your opinion is the 650 worth the extra money over the 630? Does that extra 20,000 in contrast ratio really stand out? These two models seem to be the two choices that i have narrowed it down to.

Sorry for responding late, but I did not have the lamp at immediate reach. Now, I verified it, and you are right. Mine is not working, either. I refer to center LED labeled #58, with the tag 730, which does not turn at all when all the rest do. Somebody could say that 730 (nm, I suppose) is beyond the range of human visión, but I guess that at least a dim red light glow should be emitted. Regards. Alvaro.

I've had mixed behavior on mine. The LED on the first port works as expected, each of the other LEDs have been irregular. I've noticed that if I restart my PC, the LEDs don't always come back on for ports that are enabled (even though the ports may be working). Other times I actually have to toggle the port on/off to get it working after a PC restart... and the LEDs may or may not come back on to reflect the status. Short answer; mine acts weird too.

I saw the LN32A650 and LN32A550 side by side. The white of the 650 was whiter and the black, blacker than the 550. I bought the 650 and am very happy with quality of the picture.

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good. Generally, you would have to replace The whole display module.... But I might be wrong. :0/

The color display is dependent on the graphics card itself, not the CPU chip. Make sure you have a good driver installed, and you might want to reseat the card if you're still having issues.

This is right question. It is much more bluish than 5500K, I think it is about 7000-7500K. I hope it will help you.

I have both the 8500 series LED by samsung and the PN58B860 plasma. The plasma has much nicer and deeper colors. It's viewing angle is also much better and does not wash out as fast as the LED one. The only downside with the plasma is that it drains almost 3 times as much energy but if you are willing to pay this much for a TV, your electric bill should not break your bank

Thank you all for your comments and tips. Ive just exchanged the monitor for another unit and the replacement unit does not have the same first start/powering on flickering. Btw, i tested the original unit on a ps4, 2 diferent desktops, and a laptop each with their own cable but the result were the same. In the manual it stated that flickering is "normal" due to the nature of the LED backlit, and call support only when the monitor no longer power on due to the flickering. (...?)

The difference is 126 LEDs as opposed to 160 LEDs. You would think that the 160 model would be brighter, having more LEDs, however, the 160 actually has tinier LEDs packed tighter together, as opposed to the 126 which are slightly larger LEDs spaced slightly farther apart. Believe it or not, the 126 LED has a wider and brighter light spread than the 160. Subtle, but noticeable between the two.

I had to buy a second part, The first one I bought did not match word for word, letter for letter, even though both looked exactly the same, but mounting holes were different, so my advice is to try and and find one that matches what you have word for word, letter for letter, all of these LED replacements that I found were all HD, Hope this helps and good luck

Hello, That was one the biggest reasons that I went with the 530 over 330 since I read about the screen problems for 330 and 340. My 530 works perfectly fine in bright sun, of course it dims a little but you can still see it. Thanks

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 have the same model (LED) and am coming up on having it 18 months. Hope I dont have the same problem. My son got the DLP (not LED) lamp model, 61" I believe, and has had no problems with his yet in the same time frame. I have noticed a picture "jitter" and rainbowing effect on some movies.
