Here is my review of the aluminium ReyLight Pineapple Mini with a Nichia 519A 4000K emitter:
That green does look good, I was too chicken to get a bright colour so went with black.
Just wanted to add, I didn’t realise when I ordered the “new” tailcap, that it’s actually the switch housing, and comes in titanium, so if you’ve a aluminium light, it doesn’t match. I thought it was the button for the switch for some reason.
In beamshots, you’ve Reylight PK27, which I assume is Lumintop PK27, I got excited for a moment that there was a Reylight model I wasn’t aware of.
Pocket clip on this light is one of my favourites, really nicely done.
Edit to add: also thanks for the traditional review format, I hate YouTube reviews.

Nice flashlight, nice review and nice modification video, thanks man !

Oh, whoops! I’ll fix the name of the PK27 
1 Thank
A ReyLight PK27 would be cool! 
Or perhaps something with a smaller head and a smooth reflector. 
Swapping a NM1 in is the next best thing:

Did you see the 2xAAA he was making? Hoping to pick one up in aluminium when they’re available.
For me, one of the best features of the light is the 519a, so no LED swapping for me!
2 Thanks
Yeah. I saw the 2xAAA battery too.
I’m torn between aluminium and titanium. Aluminium scratches but it’s lighter.
Does the new switch do anything to stop it activating it in your pocket when you sit forward I wonder
Al is cheaper, lighter, has better thermal conductivity, for me, I don’t mind a few scratches, I can understand the appeal of Ti though.
1 Thank
The “new switch” is actually the tailcap housing. You unscrew the tailcap, pop out all the switch guts, reinstall switch, rubber boot and button inside the more shrouded new one.
Last I checked, only available in Ti so looks daft on the end of a anodised aluminium light.

Here’s a photo of the new tail cap:

Yup, I have one of those tailcaps ready for when I can source another unobtanium 10440 after the last one died from switching on in my pocket all day…
I was referring to the ‘reverse-clicky tailswitch’ mentioned in the review and whether that new design was more resistant to pocket activations 
The reverse-clicky tailswitch seems the same as my copper Pineapple Mini.
I suspect that the tailcap with raised sides will be more resistant to pocket activations but I haven’t tried one.

Nice runtime charts! I like my Alu pineapple but the switch is super easy to activate if you crouch or bend and its clipped to jeans pocket.
Wish there was a twisty version!

The torch continues to produce less than one lumen for 5-7 hours while using a Ni-MH cell. My DIY lumen tube cannot detect less than one lumen. At some point, the voltage is too low and the torch starts to flicker.
Ni-MH 100% was flickering when I checked at 8 hours 25 minutes.
Ni-MH 20% was flickering when I checked at 10 hours and it continued flickering beyond 12 hours.
Ni-MH 10% started flickering at 8 hours 42 minutes.
Ni-MH 2% started flickering at 18 hours 45 minutes.

Here is my review of the orange ReyLight Pineapple Mini:
I like my Mini-Pineapple green on a NiMh as a bedside light for its very low, floody, warm moonlight mode. I have an Orange on order for its shrouded tailcap.
Thanks so much for the runtime graphs, they reveal so much useful information.
We can see on NiMh that it highest sustained output is only like 45lumens, and its max modes drops to the 10% level (~27 lm) in under 3 min which is kind of odd. Regulation after the drop seems good and flat, though. As a bedside light I only use the moon, 2%, 10% so it works well for me. I prefer the non-shrouded tailcap for bedside use.
Outputs and regulation on LiIon seem more reasonable given the size and battery capacity of this size light. On LiIon the regulation isn’t as flat, but maybe you get a longer runtime on each level in return. I like that on LiIon 100% & 50% there is a secondary drop then flat level at about 30 lumens for 30min.
