Well after 6 months of waiting the last of the GT90 kits FINALLY arrived!

I already sent messages to the people still on the waiting list.

At least one has understandably decided to not finish the order so I have 1 extra GT90 conversion available to anyone that wants it.

You can send me a PM if you are interested.

Looking at this picture, credit to 1Lumen, it seems you do need button top to make contact.

Typical workarounds would be to remove the reverse polarity protection board or else you could solder blob flat top cells. Small magnets may also work, but it is probably not worth the risk of a short circuit.

Yes, all the large GT based lights have polarity protection and need button top cells.

The risk of a short circuit with 8 cells in the carrier is just too high to not have the polarity protection from the factory.

Of course what you do once you have it is your business but not supported.

Personally I just solder blob all my cells, works great and allows me to retain the polarity protection. I will admit I have put cells in backwards before just from not paying attention.

LOL, I still think the box idea is a really good one, just for a different style of light.

Interested in converting my GT to a GT90. Is there a source for conversion kits or a part list?

Sadly I sold all the GT90 conversion kits and they are not open to selling me more last I checked (plus not sure it is worth it, took me over 7 months to get the last batch in).

Doing the conversion manually is possible, there is a thread of someone that did it but takes a fair amount of extra effort and work to make it happen and still counts on getting some of the parts from lumintop.
