Thread: LED has finallly surpassed HID in my opinion.

  1. #1

    Default LED has finallly surpassed HID in my opinion.

    Got my GT94 in the mail today so I took it out and took some quick beam shots of it compared to some of my other lights. In the line up are the Acebeam W30, Thrunite TC20, Thrunite TN40, Tractor Supply 35 watt HID, Firefoxes FF4S, and the GT94 of course. Yes the GT94 is much bigger than the FF4 but the fact that it is so much brighter than one of the brightest HID flashlights out there seems to indicate that LEDs have finally closed the performance gap with HID. Also the GT94 can maintain turbo till the batteries are dead. I don't know of any HID flashlights of any size( and there are some big ones out there) that even comes close to the overall performance of the GT94. It was independently measured at ~20,000 lumens and ~1.5mcd. The pics speak for themselves. Distance to the trees is about ~440ft.

    >Got my GT94
    Who makes that?

    Are all of your example LEP type lights?

    When you say "zoomed in" you mean - adjusted for maximum throw? That would be zoomed OUT.

    I don't understand why the W30 "zoomed in" has a very bright flood AND a narrow but very bright hotspot.
    In contrast to the first W30 image, with a less-bright flood and NO hotspot.

    GT94 is Lumintop. I got mine a few days ago.

    GT94 is four (4) SBT90.2.

    Its manufactured by Lumintop but its commonly known as the BLF GT94 as it was a community developed light from the other popular flashlight forum.

    No, only the W30 is an LEP light. The GT94,TC20, and TN40 are LED lights. The Firefoxes FF4 and the Tractor Supply lights are HIDs.

    "Zoomed in" as in I zoomed in with my camera on the hotspot. The first images were at the wide angle end of the zoom range (24mm full frame) while the zoomed images were at the telephoto end of the zoom range(70mm full frame).

    The whole point of my post was to say that there is now an LED light on the market for a comparably cheap price, when compared with the highest performing HID lights, that has substantially more lumens and equal or longer range that can run indefinitely without overheating. There is no HID flashlight that even comes close to my knowledge. Durability wise maybe those very expensive HID lights still have an advantage,I dont know, but performance wise there is no comparison.

    Does it have active cooling of some kind ? Heat sinking alone can't do it, not even massive heatsinks.
    If it was submerged in water the heatsink fins alone MIGHT be adequate.
    Most of the active cooling you see on units are a joke and an afterthought.
    How do you know it is not dimming after a few minutes ?
    How do you know the LED's are not getting overly hot "overheating" ?
    The death of LED's is excessive heat.

    I need to make a small correction. I said indefinitely when I should have stated till the batteries are dead. On turbo the batteries are dead in about 15 to 20mins. On the other forum there are guys who tested it and the light reached a maximum temp of 100c before the batteries were depleted. All the internals are rated for 125c and can sustain higher temps for short periods of time. The light is passively cooled and has no fan. It weighs about 8lbs with batteries. The passive cooling is so good in this light that the bigger issue is the battery temperature. The batteries will nearly reach their temperature limit after an extended run on turbo so that's something to be aware of while running the light on turbo.

    125C = 257F that's well above the boiling point of water at sea level, 100 C is 212 F the boiling point of water. For good life anything above 80C is not desirable, 60 to 80C maximum is much preferred. That's the temperatures at the LED's junction you won't see that externally on the heat sink fins, it will be lower. If its 100C on the fins the LED's are getting far too hot, maybe even 125C or more.
    Sounds like this light will burn your hands on the fins after 10 minutes or even less.

    Gotta agree here, that LED is impressive, but impractical compared to an HID spotlight.

    Here we go again. lol!

    I'm starting to think it should be standard practice to define what one means by "surpassed" when making a comparison between LED and HID, and that everyone commenting stick to within that definition.

    Having said that. I love the pics! Especially when comparing the W30 to the GT94.

    Who needs to see the light at the end of the tunnel when you have friends on CPF?

    I think we have a few technologies that compete well with h.i.d.
    1. L.e.p. (laser excited phosphor)- a mile of throw but only about 500 lumens
    2. Luminous SBT-90 Gen2 l.e.d.- a mile of throw and over 5,000 lumens
    3. L.e.p. (light emitting plasma)- 10s of thousands of lumens, bulb the size of a grain of rice (lots of potential for throw), no issues with heat (requires a lot of power though)
    I think where h.i.d. still excels is sustained high brightness for an extended runtime.

    I guess my comments brought us back to reality somewhat.
    Each technology has its place.
    Dogmatic black and white statements made earlier in this and past threads on this subject simply don't "cut it".
