*Lumen output was measured after modifying my lumen tube to make a reasonable attempt at measuring output from a light with a large diameter head like the GT98. All of my lumen output testing is done without active cooling unless mentioned in the review. I suspect my readings are on the high side, but they will give you a general idea of what this light can do. I’m curious to see what other reviewers report.

Pros:

  • A massive chonky beam of light
  • Build quality is above average
  • Can be used with the extended battery tube, or the short tube
  • Useful spill/flood in addition to the chonky beam
  • USB-C Charging - PD & QC protocols available
  • Powerbank functionality
  • Batteries can be accessed & replaced

Cons:

  • Price - very expensive
  • Big/cumbersome
  • Generates a lot of heat
  • Output steps down fairly quickly

Summary: ★★★

This light is a pure novelty. It is BIG, and with that, it is cumbersome. I purchased this unit because of the uniqueness of EIGHT, eight SBT90.2 emitters in a form factor very similar to the well-known BLF GT94/GT94X. The CRI measured at 65CRI. The CCT jumped around depending on where the sensor was within the beam, but the range was 5100 - 5500k. On the lower output levels, I was getting quite a bit of green tint, but this lessened as I ramped upwards.

Relative to the light, the output doesn’t drop significantly during the first 30 seconds and remains steady until 60 seconds. After 60 seconds, the light becomes hot, and output starts to drops quickly. At the five-minute mark, the light is extremely hot (uncomfortable to hold) and has decreased output to about 4,000 lumens. At the 5 min mark, I concluded the test.

The build quality is above average. The USB-C port and onboard charging work very well. You can remove the four screws on the battery contact plate to access and replace the included P42A cells if you'd like - use a 2.5mm hex wrench. I found the beam profile to have a super chonky hotspot but a usable spill, albeit with many "rose pedals" present in the beam at close ranges. I was able to illuminate a skinny communications tower at 500 meters in urban lighting without any struggle. The UI doesn't suit this particular light - I believe it to be Narsil. The default on my light is smooth ramping with instant access to Turbo (double click). At this light's price point, I'm left wanting considerably more. It is a unique light with the "wow" factor but cannot sustain high outputs for very long. As I mentioned earlier in this review, it is a novelty item that can't quite make its way into the practical realm as some other high-power lights do.

That’s certainly bragging rights.

Happy New Year

Happy New Year to you as well!

The light was an overall disappointment for me - at the price point, I expected a lot more. That’s the risk I took though, lol.

Sixty-one special fixed quadruple 150-centimetre mounts were produced in an effort to extend the range of the 150 centimetre searchlights, however these proved unsuccessful.

Thanks for this review. I believe I will bypass the GT98. The measured candela for my GT94X with long tube is 1.8Mcd at a distance of 20 meters. I’m really happy what I got now.
To me the GT98 just has got much more spill in the front of your feet.

Thanks for the review. About what I expected, and just like the 94x, this light is purely a novelty and barely usable for anything other than the ‘wow’ factor (which I get from my HK90).

The Wuben A1 remains the best implementation of a multi Sbt90.2 light. Period. Lumintop effort falls short (although it can be had on sale for under $700) but is a step in the right direction. Imalent or Fenix….waiting on you now!

If you cant use it to bludgeon your attacker, you’ll certainly be able to torch him to a crisp.

I didn’t realize this has onboard charging capabilities. USB-C Charging - PD & QC is even better! But do I really really need another GT? Thanks for the quick glimpse.

The onboard charging is great, and it makes for a nice war club if the short duration turbo doesn’t have the desired effect.

The spill kind of makes this light hard to use, even out in the wide open. You get so much bright spill at your feet that it messes with your eyes for the stuff that is further away. Four SBT90.2’s seems to be a better configuration for a multi-emitter of this type set up.

Thanks for the feedback. I know what you mean about having too much light in the foreground while trying to view distant objects. Your eyes become less sensitive to the light downrange, rendering the light far less effective as a thrower. Im sure you’ll still have a lot of fun with it, and the USB charging makes it so much more convenient while dealing with 8 cells.

If I spent $1000 on a light, I would want it to be no less than 100000 lumens or else have something else extraordinary to justify it.

I don’t like Narsil, but you can turn the thermal step down off completely.

I would not think of using on board charging for an array of batteries like that.

I’ve been very tempted to get this, but I ended up getting the Mateminco MT90P. I have to say, it’s pretty incredible compared to the other 30+ lights in my collection

That’s an impressive flashlight! Thanks for the review Tirarcova. :beer:

You’re welcome!!

The MT90P is beastly. You can EDC it, but you’d need a pair of JNCO jeans…lol

Hello, could you make some chart? With ceilingbounce maybe? Does it stabilize more than GT94X :poop:?

I think a ceiling bounce may cause permanent eye damage with this thang.

Too much money on such a big light if it cant sustain a certain amount of lumens.

Does it come with a lanyard? :rofl:

I will not be doing any charts for this - thank you for your interest though!
