LED Lights

Warm white LEDs are a problem. Some phospors are now ready to convert LED emmision to the lower 'temp' light but lower in efficiency. LED lights (white) work by using phosphors to convert the high efficiency emission to 'white'. Yea, LED flashlite problem is getting rid of the heat. A dc-dc converter to get batt. voltage to LED voltage is also a PWM device that allows dimming. 70% efficiency generates a lot of heat the lite cannot get rid of. Got a high brightness penlite that attracts small bugs that fry on the lens.

Thing is with LED's.
I have an old, model 32- 61 Oeheler Chronotac chronograph. I was using it at an indoor range and they converted from incandescent to LED's , then it no longer worked. I thought it had finally gave up the ghost. Till I set it up out side and it worked. I wonder if this is just an issue with my antique chrono, or if other people have had Chronographs or other light dependent devices that will not work under LED light?

I sold the 2002 Suburban and bought a 2010 4Runner, and I switched all of the internal /external small incandescent bulbs with LED. Before I posted in this thread I had purchase the LED kit to replace the main/low beam lights with LED's, with a passive heatsink (I wanted something without a fan). So I replaced them over the weekend (yes, the truck had two different brand bulbs in there!):
Passenger side:
Driver side, more cramped due to the battery being "in the way":
Pretty significant difference in brightness:
Stock:
LED:
And of course, at night, the difference was significant as well. Too bad these arrived AFTER my camping trip to Arkansas, as it would have been great to have these installed with the night driving I did, specially Friday night. But at least I have them now

And us old people with cataracts hate you when you drive towards us. We are blind for three seconds after you pass us going the other way.

Rick, the OEM's are going with the ridiculous, blinding LED or HID on all headlamps now, I feel your pain but there is a solution: Apply a 2x4" panel of electrician's tape to your windshield in the area of oncoming lights. If you get it in the right place you can hide behind it.
Will, the problem isn't cataracts, it's the effects of the surgery and implants after they are removed. Same thing with Lasik surgery, light sensitivity, especially at night, is significantly increased. Piercing blue headlamps are especialy painful. To make matters worse, stupid/incompetent/lazy drivers coupled with incomprehensible automatic headlamp controls makes for a 2/3 majority of drivers who run with their high-beams on all the time and that hurts me like hell even during the day. Pickup-trucks pulling trailers or weight in the bed, and/or with a "leveling kit" which raises the front and nobody bothers to re-adjust the headlamp through, make it so even the low-beams shine directly into the windshields of oncoming traffic. Motorcycles are also really bad about blinding drivers with poor lamp adjustment or running high-beams on all the time, I guess they just don't savvy that I can't see you if you BLIND me.
I have an interest in the LEDs for the "torch of God" effect which will enhance what I already do...carefully aim the left high-beam directly at oncoming drivers faces so my "DIM YOUR $@&$#&^# LIGHTS" blip has maximum effect.

Oh no . . . Trust me it is the cataracts before the surgery. Driving at night with cataracts gives the effect from ANY light the same as a fireworks show and of course the brighter the light the worse/more intense the effect. I was to the point of couldn't drive at night at all, if I was out & about and it got dark I had no choice but to call someone to come get me. Markedly better after surgery with the implants.

my old eyes are really bad for night driving, so much so, that I avoid night driving, if I can.
BUT, what does help, is a visor extender...I have one like the one in the link, where there is a second adjustable dark layer to position for oncoming headlamps...it helps, so at least I am not blinded...but the dark filter does limit my vision of the ditch for oncoming Deer

At the casting bench in the sky. RIP Bret.
My '95 Burb had aftermarket HID headlights. Far as I'm concerned they were worthless. Low beam was bad enough, high beam was like a dim blue glow. I avoided night driving with it when I could. They were just awful. I would have gone back to stock halogens, but apparently the kit the previous owner used required removing the stock headlight buckets and wiring!

Ian, I solved it by buying a stick on blue blocker plastic sheet (6x14) for the top of the windshield, when I see one coming I lean forward and sit higher so my eyes are above the lights. Cataracts come in different colors, mine are yellow and block yellows/orange light. Blue/white burns right through them.

Blue LED headlights in cars are a real joke You need warm ( yellow light to pierce darkness especially if the is moisture in the air)
Yes they are bright to oncoming cars but but to the driver distance is limited especially in moist conditions.
A mater of physics of the air
