Product main parameters
Part Number：FOR RLC-117
Compatible Model: For Viewsonic PG705HD PG705WU PX727-4K PX747-4K Projector lamp bulb.
- Lamp life results will vary depending on mode selected, environmental conditions, and usage. Turn off this product when not in use to prolong the life of the projector.
- Never touch the glass portion of the lamp with your bare hands; the invisible residue left by the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.
Extended service life
The latest generation of A+ wick, with optimized burner design, allows aging at any position. While the brightness is increased to more than 90%, it greatly extends the life of the bulb. The brightness will be slightly reduced after 4000 hours. Other products on the market have longer life and more stable output
HD image
The high-purity quartz bulb assembly can withstand the high temperature and pressure during work, and is equipped with a high-performance matrix light control to present you with more high-definition picture vision, which is safe and reliable to use.
Realistic colors
The inner wall of ctbaier's bulb is equipped with a special coating, which reflects 100% of visible light and absorbs harmful ultraviolet rays, so that every presentation you have can present vitality and vivid colors.
Professional because of hard work
While the brightness is improved, the life span has also been significantly extended. Through continuous improvement and innovation, companies test bulbs in different series and different environments. Collecting the data generated when the bulb is working, while using high-quality raw materials, combined with professional production technology experience, our products can meet the use of multiple scenarios and fully meet the needs of customers.
How to extend product life：
- Do not disconnect the power suddenly during use.
- Each use lasts at least 3 minutes, preferably not more than 4 hours each time.
- Do not turn on or turn off frequently in a short period of time. Before unplugging the power plug, make sure that the cooling fan stops running.
- Replace the filter regularly.

Technically it "worked" but the brightness was so bad that you couldn't see anything. I thought maybe it was my projector but I purchased a bulb from somewhere else it was like a night and day difference

the power connector didn't mate with our FW430 projector. i had to completely disassemble the lamp and swap all the parts and the housing of the connector to the old lamp to get it working.Update. Although the lamp didn't work for me the seller did a great job of taking care of me and was very responsive. I'd order from them again if given the chance.

First, I will say that I appreciated the careful packaging of this item. The lamp unit was wrapped in a plastic sleeve, and further wrapped in a bubble-wrap sleeve, all of which was inside a styrofoam housing, inside the cardboard box. Which of course was then placed inside the Amazon packaging alongside a Sealed Air pack.Inside the box for the lamp, there was also a baggie which had an eyeglass-style cleaning cloth, as well as a nice small Phillips head screwdriver with a clear handle.I placed the lamp inside the projector and secured it. Unfortunately, my projector did not detect the lamp unit. I had this happen to me with the previous lamp unit I ordered (from a different vendor); that previous unit had exploded (after only 1709 hours, and while I was on vacation and the projector was fully powered off...). The little PCB which is on the side of the housing, which records the lamp hours, is what the projector actually "detects". With the previous unit, they had a known manufacturing defect where the PCB was not being recognized, and they shipped me a replacement unit.Unfortunately, it seems that this unit has the same issue. Re-seating the lamp assembly, and even going as far as re-seating the PCB itself to ensure that it is making contact, did not fix it, and the projector was simply unable to detect the lamp. I was able to swap the PCB with the lamp which had exploded, and immediately the projector recognized this replacement lamp, and I was able to confirm that the lamp works. However, of course that means the PCB now has 1709 hours on it, instead of 0.If the manufacturer is able to send a replacement (even if it's just the PCB itself), then I will update the review to 5 stars, as this was the only issue I had. The manufacturer clearly puts the effort in to pack the lamp carefully, and even includes the screwdriver and cleaning cloth, and the unit was shipped to me quickly.
