ywh:

I recieved my bulb in perfect condition, and installed it in the reflector - Thank you!

To anyone who's interested, shipping time to Canada/Ontario (which varies), for me was 12 days. Bulb showed up decent packaging without any defects or signs of abuse.

On another note, I didn't really expect to replace my old bulb, but I did want to take it out of the reflector to see if I was capable of replacing it myself.
The most difficult time I had was adjusting the new bulb inside the old reflector because I did not MEASURE THE DISTANCE the bulb sat inside the reflector.
I've attempted to adjust it three times now, and it is very good, but I could probably get it a bit better. The colors are vibrant, and the brightness is very good.

I definitely recommend purchasing a bulb from ywh if you're in the market for a quality replacement bulb on the cheap.

Greg.

something wierd
i purchased a 170w bsm-ac-h from ywh
projector is epson emp-82

i just installed it using metalsteel epoxy ( resistant to high temps )

the brightness is great

An externally hosted image should be here but it was not working when we last tested it.

now ive noticed the lamp isn't allign completly straight
can it be the cause? im not good with optics but in my mind it should be responsible to brightness and contrast only not the uniformity of the color

hope i can fix this
thanks 🙂

To me, that looks like the colouring of the reflector and probably due to misaligned lamp:focal point of reflector.

the placement of the arc in correct focal point of reflector is extremely sensitive. small movement of even a single mm makes a big difference. see if you can tweak or move lamp around until problem ceases
