To answer your question. The Toshiba 9011 lamp has not been produced by Toshiba for around nine years and any stock available is old stock and even left over counterfeit lamps (most likely).
The Philips HIR1(was 9011) - its proper name - is much brighter and does not suffer from the spherical errors that the Toshiba lamp had. The Toshiba bulb was made that way to light up further down the road but limited spread left and right because the light emitted through many many angles of the bulb and did not concentrate in the lens reflector. Think of it as a house lamp that shines light in 360 degrees of non-concentrated light. The lens reflectors want the light focused on the back and sides so it can be "thrown" forward through the front of the lamp, and the Toshiba's design 'threw' too much light forward.
The Philips ** "Third Generation" lamp rids the lamp of 'spherical errors' and a decade of technological advances lead to a much brighter and much longer lasting lamp. It also does not need the HIR coating that was used originally to maintain a higher Lumen output throughout the life hours of the bulb.
Life hours is the point in which 80% of the original lit bulbs are still lit but perform at 60% (+/-10%) of its original efficiency and luminosity. The Infrared coating of kept this efficiency up to 75% (+/- 10%) However, this was late Seventies / Early Eighties technology and has been made obsolete with newer manufacturing / metal and gas technology and the coating is not needed to pass the DOT and Euro Reg 37 specifications as originally specified. I think though that Philips is still developing this lamp and may bring back the coating to make a +30% version or what the old timers call Bright Light Boosted or BLB. I only say this because we had a shipment that we noticed what may have been the infrared coating. It was sad because we noticed it on the last bulb being shipped out and did not get to test it.
Either way, the biggest bonus for those that have to remove the front end of the car and rear axles to replace the lamp..... the lamp life hours are significantly longer and the 9012 lamp is the perfect upgrade to 9006 based fog lamps due to extremely long life.
Hi Beam stock: 9005, 12.8V, 65W, 1700 lumens, 320 hours / Hi Beam ... HIR1(9011), 12.8V, 65W, 2530 lumens, 400 hours
Lo Beam stock: 9006, 12.8V, 55W, 1006 lumens, 360 hours / Lo Beam ... HIR2(9012), 12.8V, 55W, 1875 lumens, 1000 hours
Life and output always vary with voltage input, wiring size, and lens reflector condition
** Third Generation. The original late Seventies GE design was actually a forerunner to the shape and make of today's HID lamps. This was the 'First Generation.' The 'Second Generation' lamp was the Toshiba lamp, and, well.. Philips is the the 'Third Generation." The "generations" thing, although each was an improvement over the other is more marketing hype than anything else.
