Group Buy Now Live - BLF GT90 SBT-90.2 powered 5,000 Lumen, 1.8Mcd / 2600m Super Thrower

The last GT90 conversion kit sold a few days ago BUT seems that lumintop is in need of some cash and are willing to sell me a few more out the back door.

I am putting together an interest list for those that want a GT90 conversion kit for the GT or GT70 (same kit works in both).

If you are interested send me a PM quickly as the number of interested parties will determine how many I get.

Hey Ace… got my SBT90.2 kit today…nice packing job… everything looks good.

I see what you mean by needing a better/real centering device :person_facepalming: … I have a couple Idea’s…

If you are careful when you tighten the head down, it puts enough pressure that it should stay centered unless you really bang it.

Long term though I do want to make some custom centering rings that fit better though but the 3D printer is still closed at least until next month last I checked.

In other news, I will be placing the order for the GT90 conversion kits on Monday. While I plan to order a few extra kits I can’t afford to be left holding a bunch of them.

So If you are interested, let me know.

I would be interested in 2 Bare MCPCB and 2 DriversIF possible

. In other news… found some of those lighted tail switch white plastic washer’s that are a bit oversize .008” to the I.D. of the centering device. The white washer I.D. is snug 5/16” so I spun it up in the drill press using a 5/16 bolt with the head cut off and 2-5/16” nuts (home made arbor) to trap it. Left about .002” press to the I.D. of the centering device.

It pressed fit in nicely…tight enough to drill out….???

I would not like to use a fitting centerpiece and have that heavy reflector banging on the solder joints, but rather glue the existing black reflector positioner on the MCPCB.

Not a bad idea.

How would you center the centering block to the LED? Go off the MCPCB holes to the Block?

Thought about drill/ream for 4mm dowels .The block, MCPCB (is really close to 4mm so a slight ream should do it) and the body of the light. Some short 4mm dowels to locate it all, and then just the clamping force of the reflector to hold everything down.

this will do for now…

Not planning on mounting it to a Howitzer… :stuck_out_tongue:

Looks like they are finally getting ready to ship out the GT90 kits late this week or next week, I once again decided to pay the extra for express shipping due to all the covid congestion on normal mail, so we will see when they arrive.

Looks like I will have 4 extra kits for sale based on the current numbers, so anyone that wants a GT90 conversion kit, let me know! I highly doubt this will happen again.

Groupbuy price for gt90 is not valid anymore ?

I don’t think so, the code still works but I think the price is $300 now.

I wonder if these are taking forever to get here…
(Looks at his gathering dust)

Are these shipping now? Running full steam?

Is this 5000 lumen or 7000 lumen since the nealsgadget site says 7000 and this thread says 5000.

It is a bit over 5000, they inflated the numbers for the advertising at lumintop it seems.

The VOB review video shows the numbers he got.

I keep hoping to have an official update to post but they have been real quite about the GT90 kits the last few weeks sadly.

They said they would be shipping out “next week” over a month ago. Then I got a message saying that they are missing 1 part to the kit and they will ship as soon as it is back in stock. I have asked repeatedly for more details ever since but nothing solid yet other then they will ship when they get the parts.

So they should still show up at some point but no idea when at this point. Good thing I don’t take payments before having items ready to ship unless I truly can’t help it lol.

When they do show up, I think there are 2 kits left unspoken for.

I put my hand up for 2 but have since killed one so I will take another 1 or even 2

PM inbound

I was re-adding the numbers on the list, looks like I actually had 3 available.

Hope you are including me for 2 of these? Think you told me that a while back.

Yep, got you down for 2 of them.
