BRZ D4S bulb ?

[Sportsguy83]

Im not referring at you. I understand your point and agree with you. I just meant it for the colors that go below halogen.

gotcha, sorry i wasn't sure...

but you know, even @ 12000k [ricer purple] is ~2000lm and 2x brighter than standard halogens, so...

it's no surprise, but HIDs at almost any temp. is still brighter than halogens...

This is not correct.

Standard OEM halogen 55W 9006(HB4) = 1100lm (lumens)

4300k D2S Philips = 3200lm (lumens)
4300k D2R Philips = 2800lm (lumens)
4300k D2S Philips = 2400lm (lumens) actually 5800k
4300k D2R Philips = 2000lm (lumens) actually 5800k
4800k D4S/R (brand) = 3800 (lumens) ** brightest in the market
5800k D4S/R (brand) = 3300 (lumens)
7000k D2S other = 1790lm (lumens) *(other bulb brand)
7000k D2R other = 1390lm (lumens) *(other bulb brand)
8000k D2S other = 1180lm (lumens) *(other bulb brand)
8000k D2R other = 780lm (lumens) *(other bulb brand)

At 8000k you're already down to Halogen levels of output, not anywhere near 3x the brightness.

too much mixed info on the web, no way to tell what's really correct...

as stated before, i've personally ran 8000k with zero visibility issues and would have a very hard time believing it's output is roughly the same as conventional halogens...

i don't want to get too technical, it works just fine for me, so i wouldn't worry about it...

So you would recommend staying with the 4300k for optimal night time visibility?

The highest I would ever consider going would be 5000k, but 4300k is pretty much accepted as having the best illumination. The actual lumen output of the bulbs will depend on the manufacturer, I'm a big fan of Phillips.

Pretty much; the only problem is your visibility outside the lighted portion of the road is so much worse because of how bright it is INSIDE your lighted field of vision. Not sure if that's the bleaching of receptors that a previous poster was talking about, as I didn't look it up. Essentially, the differential between lighted and unlighted is so great that you don't have night vision. Light a match or ignite a lighter in the dark (after your pupils have dilated) and stare at the lighter: you'll see that while the lighter is bright, the area surrounding it is MUCH darker than it was without the light.

Thanks guys. So depending on the actual lumen output, 4300-5000k will probably be where I want to stay. Looked on amazon, and it seems replacement bulbs will run $40-50 a piece.

$40-50 is about what you'll be paying per bulb, and I would stay away from eBay since there are a lot of counterfeit bulbs. If you're a real baller you can look for Phillips Ultinons which are illegal in the US but put out crazy amounts of light, they only set you back $200 a pair

These guys?

Note: These are the D2S version. Do they make these in a D4S?


Btw Longhorn, what would it take to go from the D4S 42V to a D2S 85V? Need a new HID ballast?

12k are generally going to be LESS output than stock Halogens unless you believe the sellers who still say 2000+ lumens for 12k (I've yet to see a 12k bulb put out any worthwhile light). 8k is about or slightly more than stock halogens. 4300k are twice as much as stock halogens. You consider that loss minimal?

Also remember (since this is the BRZ forum) we are talking about D4S bulbs, which are ALREADY lower in output than the older (and arguably better functionally, if not environmentally) D2S bulbs.

If you want high temp bulbs for the color, that's fine, but let's not try to convince people who may not know any better that it's an improvement in lighting.

halogens tend to be around 1500 lumens unless it's a colored or cheap bulb. Are you really going to try to convince use that 6k HIDs (around 2500-2800 lumens at best) is 3 times higher than that?

Based on them Halogens have ~800 lumen output. Perhaps if you paint the bulbs that might be true.

Quality Halogens are generally ~1500, some 1700, some over 2000.

Those HID ratings are the normal the sellers of these cheap chinese digital ballast systems quote. My only reply to that is "good luck".

Ballast, not sure if the burner (bulb) plug is different or not with D4S since I've never had a D4S system before but the ballast is definitely different.
