SST-90 Smooth Aluminum Reflector (7.3CM-Diameter)

Pros: Measured at 73mm as stated, works well with a Cree XML. Hotspot is about twice as bright as a Trustfire X9 (modded with the 2.8A 7135 driver DX sells) from an XML U2 LED ( the Trustfire uses a ~55mm reflector and T6 ).

Cons: A couple of very slight defects in the finish however they are too small to be noticeable in the beam. Price could be better, however that is the drawback of buying large items from overseas (as shipping is included), still not bad at $9.

Other: If you need a big reflector for an XML and have a housing to put it in get this, with a well driven XML you can easily see out to 300m with the outlines of trees past 500m, add a copper bonded XML and you have one of the best LED reflector throwers money can buy.

Pros: Really tight beam and a large spill.

Cons: Easy to scratch, fingerprint and dust magnet. SMO reflector means slightest misalignment is going to show up as beam artifacts.

Other: Great if you want to build a thrower. There are mods in the internet using this reflector and aspheric lens to make mega thrower lights.

Pros: I got 4 of those. All of them in perfect condition. The beam from SST90 or SST50 LEDs are very nice, round and even. Good choise for long range LED torch, or as extra lights for your car.

Cons: None.

Other: These reflectors are a very good choise for SST 90 and SST 50 if you want to make a long range LED torch.

Pros: Throw, and Tons of it. I'm only using this reflector with an xml(an over driven one) but it has more throw than any HID I've ever seen. I can only imagine what it does with a dedomed one. I have lots of land around the house and at 500 ft this lights up anything like daylight. My nearest visible neighbor is at around 1000 ft and I'm afraid he'll complain that I keep spotting his house. Yeah it reaches that far.

Cons: 1. Lack of pill 2. Extreme care must be taken of finish as it will damage fast. 3. Conductivity (this is true with most metal reflectors) as it will short out emitters if not protected. 4. A pain to properly focus an xml, but WE'LL worth the effort.

Other: If you have a host, I highly recommend this product. From what I hear it works really well with most emitters. Buy it
