Part number and Best source for Phillips H9 HID bulbs

My PIAA Hyper Arros high beams are getting long in the tooth. Would like to try the best Phillips H9 HID bulb. German if possible. What's the part number and best source? Thanks!

 

Not sure if these will help or not but have them uploaded already. Also can’t help sourcing them. My local parts store sells them for nine bucks a pop
Oh wow I can’t read! Leaving this post for the h9 packaging

 

HID in high beam application is not a good idea, because HID takes a little while to fire up. Flashing brights at someone won't have the desired effect. You want a good LED bulb or just stick with halogens.

 

There are NO good LED bulbs. No drop in LED bulb matches halogen bulbs in filament placing, filament size and being able to produce omnidirectional light.

^Beat me to it

 

Hyper Arrows are blue tinted halogen bulbs. Putting tint on the bulb lowers the overall light output of the bulb. That's how tint works.
Clear bulb will be brighter than a tinted bulb of the same wattage and design.

 

Some will never stop, but one person conceded the fight and returned to H9 halogens.

 

The H9s I get from NAPA have no tip coloring. They may not be quite as bright as Phillips (or maybe are ...) but they work well enough for me and I do not Crapzon.

 

But that's not as cool as 6k white light. Looks cheap because that's all that matters.

On a serious note you are right.

This is what OP referenced, I assume. Wholly colored blue bulb.

Yep. I read that article 10-15 years ago. Very good info there:
"In fact, you get less usable light from such a bulb than from a regular clear bulb, and here's why: A blue filter removes nonblue components of the light passing through it. Halogen bulbs produce very little light in the blue frequency range. When you put a blue filter on the bulb or lamp, you are reducing the amount of usable light that gets from the glowing filament to the reflector, to the lens and from there to the road."

 

I "upgraded" to Sylvania Silver on my Corolla when the first bulbs died after 5 years. All blue and silver-tip ... if I only knew then what I know now ...

 

Amazon gave me German made ones

Scroll to the bottom of the post: https://www.tacomaworld.com/posts/21739043/ Hikari Ultra for example was 20% brighter than stock Philips H9 in the high beam application at 42 ft. The challenge is finding Hikari Ultra in H9/H11 size as they appear to be discontinued. I did find them on clearance in 9005 size for my 4Runner high beams, and there they are a massive improvement over the stock halogen bulbs



If @tonykarter wants white light, Philips Pro9000 comes close to H9 halogen performance based on testing: https://www.tacomaworld.com/posts/25638197 It's readily available: https://www.ebay.com/itm/134773851482

 

And???? My point stands.

From your link to crash's thread and Hikari Ultra testing:
LED thickness 2.64mm vs 1.42mm of the halogen filament thickness. LED is 86% thicker.
Light output: LED 224.4 lux, vs 257.9 lux of H9, or 13% LESS bright than halogen.
"The halogens maintain a bit of a better recognizable hotspot than the Hikari's, and the halogen peak beam intensity is up near the cut off, vs the Hikari where it is a little lower. The peak beam intensity should be up near the cut off to carry the projection as far as possible."

From you second link, Phillips LED thickness is 2.85mm vs 1.42mm, Double the thickness of a halogen filament.
From the link: "Philips LED pattern only. Note the lack of uplight and shorter pattern height...Note the difference in uplight and vertical height of the pattern, which makes sense when a replacement LED only projects directional light horizontally."
Phillips ARE brighter than stock H11 at 195.9 lux vs 144.1 lux. But H9 halogen is 257.9 lux, ie 32% brighter than Phillips.
So you get less bright white light, which does not light up as efficiently as halogen H9. This is an upgrade????

For true 9005 replacement, look into 9011 HIR bulbs. Same filament size as a regular halogen, same omnidirection, but brighter and whiter.
That's what I use in a projector Low beam and a reflector High beam RAV4 going for 2 years now. Same cut off point, same uplight, same hot sport as 9005. Just more light.

^Did you keep reading? For high beams the Hikari is 20% brighter than H9. OP's application is high beam. No cutoffs.

 

I did. This part? And it is a good thing?

"The LED pattern is a bit more filled out than the halogen that has a hotter area lower in the beam. But that isn't unintentional. The lower hotter spot in the halogen high beam is to project the beam maximum forward distance for down road distance vision while also giving a wider area illumination. The LED pattern has lost this defined hotspot trait and is more of a uniform light spread. I did some 42' distance testing for high beam, and the Hikari's put down better peak numbers by roughly 20%. However it wasn't easy to tell exactly where that was relative in the beam and I suspect it is higher, for example a 20% increase in light aimed up 5 degrees isn't going to be beneficial to help you see further down the road. Brighter yes, but you also want that brighter applied to where you need it to go for it to be true effective."
