Hello,
I have a Christie CP2220 and we project both 2D and 3D (using RealD). I've been asked to get another 1.5 ft/L for 3D and just can't go any higher on the CDXL-30 Lamp. Does anyone have any experience with the CDXL-30SD Lamp? The literature states that it'll support 22,000 Lumens vs. 19,000 for the CDXL-30 but with almost identical power requirements.

Does anyone knowledgeable with these bulbs know if the SD will actually get me more lumens?

Thanks.

-Cable

p.s. changing the 3D equipment is not an option.

It WILL get more light and probably satisfy what you are being asked.

Note, the CP2220 only gets 15,000 lumens on the CDXL-30 and gets up to about 18,500 on the CDXL-30SD.

Any of those higher numbers are promotional type things...e.g. running at 110% power (voids lamp warranty) and not sustained (great so you get a lot of light for an hour).

Thank you for the info. Just what I needed to know.

I use the CDXL 30SD. They do give you that extra boost of light but there is a cost. Only 1000 operating hour warranty and they cost a bit more. Also often have issues when at about the 500 hour mark they like to light and go out repeat a few times. They tend to get better again after another 100 hours or 2.

Make sure to use the extender adapter inside the lamphouse.They are small bulbs but be careful they are at an even higher pressure.
