Yeah, will do.....if I ever manage to decide what to do! :)

Interesting comment about the RBE. Does Keystone correction help that? I tried DLP many years agao and actually felt nauseous after a demo, I just saw rainbows everywhere!!!

Has anyone used JP-UK for bulbs? Seem to have JVC replacements for a slightly more sensible price.... Starting to edge towards a new genuine unit while I save for a new PJ.... and thinking a new genuine part may help with resale value down the line....

Brill, thanks, still expensive, but a.bit cheaper than the other genuine lamp I've seen. Thanks, Holly!

Ok gone for jp-uk “genuine” option.
keystone hides the side rainbow so lose a bit of picture but only minimal amount.
not the purist solution but hey-Ho!

Let us know how you get on.... Was that the cheap/middle/expensive option?

Middle option. £115. Delivery in two days. Easy as anything to fit once I’d realised the holding screws needed about 10 full rotations to disengage. managed to clean out the inside at the same time. It took a few hours to settle down but once it did (and I’d dialled down the settings I’d had to use on the old lamp- god that was being flogged!) it is producing a fabulous image- much better than the Optoma HD29 set up in the sitting room this summer (instead of flatscreen after it was decorated- other half delighted with that option). Really pleased. Feels like I’ve just got a new £2k projector! Go for it!

I did go for the genuine replacement and am not impressed as it doesn't seem any brighter by eye and I have spent this afternoon checking with a light meter and I am pretty sure it's no different.

I didn't clean the prism but it looked pretty shiny to be honest.

Did you notice a big difference by eye before making any adjustments etc?

Huge difference- but my old lamp was way over the hill anyway. Had to tone down pretty much all settings. I’ve finally just gone for straight out of the box cinema natural setting- looks brilliant for films, football and golf. Very happy two weeks in.

Marky1973 just double checked- my lamp reset didn’t work. 5700hrs (I knew there was a 7 in there somewhere!) Thats also without ever cleaning the filter.

Wow.... Gonna request a return on my bulb. Definitely genuine, but just no real difference.... Might as well just carry on with the old one until I upgrade later this year.

1760 isnt even suggested life of bulb! Not surprised little if any difference.
Good luck with return - hopefully will be successful- and planned upgrade. In all honesty I‘m struggling to imagine an appreciably better picture than an HD350. Then again Ive been relatively happy watching a 5700hr bulb so what do I know!

Well the bulb warning is supposed to come on at around 1900 and the average life seems to be 2000-2500 from what I've read, not 5700! But nice if you can get it! 😁😁😁

Update on the cheap bulbs, i bought 2 and they both give a slight pink tinge to the picture, it is only noticeable when the screen shows white. If you have need a cheap bulb they are ok but i wont be buying more

Does your projector have white balance adjustment that you can use to dial down the red component slightly?
