Romisen RC-E4 3V~8V Cree 2-Mode Flashlight Black (CR123A/18650)

Pros: Price for sure. I like two mode aswell. Don't need more than this, more modes just get annoying for me.

Cons: Blew the regulator when I tried putting in two 3.7 volt lithiums. Maybe this was my fault since two full lithiums is actually 8.4 volt? So then I just converted it to direct drive with a single 18650.

Other: Price is cheap and the machining and construction is very good. I like the two modes and works well as a direct drive. I'm giving this one away but I've already ordered another one as I like it so much.

Pros: - Cree emitter - light is white and bright - barrel fits a 18650 battery or 2 CR123's - long runtime on a 18650 - excellent machining and smooth threads
- 2 modes (HI -> off -> LO -> off)
- typical Romisen build quality
- Price is right

Cons: - No mode memory (but for this price, not a dealbreaker)
- Reverse clicky (might be a plus for some)
- Mine arrived with a cracked lens (replaced with my own parts)

Other: Excellent light for $16 and change. Be sure to get SKU 5776 (Trustfire Protected 18650) and a charger if you don't have them already.

Pros: + Powerful with RCR123 3.6v batteries
+ No problem taking protected 18650 batteries (sku 5776). They fit perfectly
+ Double quality o-ring at the tail thread
+ Sturdy construction
+ Very compact
+ Low price
+ Good hand grip, well balanced
+ Tight spot, though a bit weak spill

Cons: - Lens not glued and no o-ring on it
- CR123 batteries rattle a little (not with 18650)
- Reverse tail cap clicky switch (I prefer forward)
- Only one mode (DX should change this info)
- Very thin o-ring at the head
- Notches don´t avoid rolling

Other: For this price this is a good torch. Not a 2-mode as advertised but still useful as multi purpose help.

Pros: +P60 host
+Small-ish size. Strike bezel adds size I don't need.
+Romisen seems to always have good build quality.
Original module worked fine on 2 X RCR16340, 1 X 18650 (dimmer), 2 X CR123.
Emitter had a SSC like green-ish tint, only noticable next to a Q5-WC though.
It made for splendid CR. YMMV tint lottery and all ;)
Original module also had hella heatsinking on it, most I've ever seem on a P60.
It was ribbed al the way down to the base and was actually to large in diameter to fit into another P60 host. (wish china would standardize a little more)
TF protected 18650 fit fine.

Cons: Glass lens is quite thin (compared to more premium lights) and I would have expected better from Romisen.
Bezel ring is also thin and seems light it might dent and break glass if it took a header. OTOH, glass is cheap :)
NOT TWO MODE :(
O ring shifts if head is disassembled and you need to pay attention when putting it back together.

Other: Handsome light.
Versatile voltage input.
Romisen rocks the low dollar light house !
nicest heatsinking I've seen on a P60 reflector.
I'd buy again in a minute.

Pros: A fairly powerful flashlight, with good flooding over a fairly large angle. This flash light has been used by me quite a lot over the last months. It's a dependable light, which can easily be used for under a 30 seconds without much over heating.

Cons: When left on to long, past a minute, the flashlight begins to heat up a little. Slightly hot to the touch.

Other: Serious flashlight, good quality for low price.
