From our Optoma brand, we have the BL-FP230H, that supports the projector models GT750 and GT750E, which are 720P native resolution units. These models were somewhat unpopular in that many sites such as Amazon have limited, but positive reviews for overall use of a projector. Both projectors were later replaced by other models, although we still do carry this lamp for those who still have them.
The Optoma BL-FP230H as you may have noticed (if comparing) is identical in appearance as the BL-FP230D, and BL-FP190B. The FP190B only differentiates itself with a lower powered bulb. Based on certain projector needs, manufacturer's simply change a bulb's wattage, but many times the lamp housings stay the same. The BL-FP230H, as the name suggests uses a 230W Osram brand bulb, and has a good 3000 lumens rating.
