Optoma Projector Flashing Red Power Light

Bright white light is very bright. Red/red-flashing light is cool -- not sure if I'll ever use it. Good fit and balance (with batteries in back). Lightweight and comfortable. Looks suitably geeky. Very happy with my purchase.

Seamlessly works with my Optoma Projector; no calibration necessary.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

I love this one so perfectly with my optoma projector and mouthing it to Kupo universal projector mounted

but it is unsettling to have the upstream light flashing

The Epson 5050UB projector is a huge improvement over my old Optoma HD25. The colors are superb, the lens shift is possibly the best feature, and it's a super quiet unit. I love this projector and the price is the best in its class and even the next one too!

Very good projector. Better than optoma. Very sharp and good color. Good menus and easy to set up. Would buy again.

Like most people who’ve been cooped up at home for the last six months, finding an escape from the collapse of civilization that won’t destroy your marriage or damage your liver has become an Optomal pursuit (see what I did there?). This is where the Optoma Technology HD 146X Full HD DLP Home Theater Projector comes in. Def so high, every wrinkle, every bit of dander and speck of mud beckons you to step into an alternate world. A machine so quiet you can hear the zombies coming. And the remote control is nice because being able to turn the projector off without having to move from the blanket cocoon, so carefully constructed, is important when you want to sit in the dark and stare into the void for an indeterminate amount of time because time no longer has meaning, minutes and hours are null, and there are only episodes of ‘Girls’ and Adam Driver’s beautiful, giant, lop-sided face in so much def I can see every mole on it. Purchased as a gift, but really this was for me. Ideally would have one in every room projecting whatever things in the world I missed the most. Probably never leaving the house again, now it’s by choice. Thanks Optoma Technology HD 146X Full HD DLP Home Theater Projector, you’re the husband now.

This is an excellent 3D projector. There is absolutely, no cross-talk and no flicker at all, even with material that is not very well known for its 3D quality, such as Tangled, or Despicable me and Monsters vs Alliens blu ray 3D! It delivers very bright and perfect colour saturation even in daylight conditions in the projection room with very low noise! I saw no judder at all, even in very fast action scenes! The only problem is with its set-up, since there is luck of vertical, or horizontal lense shift! However, with a little effort, this is a disadvantage which can be overcome! DLP technology from Texas Instruments, and 3D-RF, or DLP-Link technology developed by Optoma, really deliver the great performance results, Optoma claims for these technologies to perform in its official site! ...And all this at a fraction of the cost other 3D projectors have! I'm off to getting the upcoming Optoma HD83 model for sure, especially if it sells at such low a price as the HD33 model!
