CREE XP-G R51B 7000K 350LM Emitter with 16mm Base

Pros: 139Lm at 1W power, 290 Lm at 3W and up to 440 Lm at 1.4A (maximum allowed by Cree is 1400ma) Completely brightest with sku.13552 3W PSU Visible difference in amount of light between this and SSC-p4 U-bin. Not so bad, yah?

Cons: Has no special optic parts - hard to create custom Lamp

Other: Useful Small Wide-current compatible. By it and see by self))

Pros: Bright LED. At the current time the most bright diode. At 16mm star. - the most expressive of XPG that can be purchased at the dx. - soldered to the star. - Reasonable price. - high light output.

Cons: - Color temperature 7000 goes into the blue. - really hot. When replacing Q3 at R5, it is very much felt.

Other: Good, bright LED, a little blue, but that's okay))

Pros: - Very bright LED. - Straight forward installation. - Official CREE LED. Just as pictured.

Cons: - This Emitter does get pretty hot. - Not the cheapest of emitters.

Other: I am very satisfied with this purchase. I used this emitter to replace the emitter in my TrustFire TR-801 Q5-WC 5-Mode flashlight, SKU 15335. This emitter is a whole lot brighter than the Q5-WC emitter, although the Q5-WC was not an official CREE LED emitter, whatever difference that makes.

Pros: great price, bright white light and perfect for a 26.5mm drop in. Works great with either smooth or op reflector personally prefer the op reflector result.

Cons: The correct reflector for this emitter is hard to find. Although it works with a q5 reflector it simply looks better when you can't see the entire emitter.

Other: Cheap repair for a faulty drop in. Works excellent with a 4*7135 single mode driver when driven at 1.4A, even with 3*7135 at 1.05A it's still a great emitter for a handy torch.

Pros: - It's very bright and very small - It's cheaper than 14mm star version (another one on DX) - It is small dome and high efficiency

Cons: - Nothing!

Other: If you need a small, bright, moderate current and efficient LED, buy this.

Pros: + Easy to solder; + Emitting very big amount of light; + Small and bright; + Not bad MCPCB (alluminium); + Cheap + U can cut a bit from mcpcb if it doesn`t fit into your project. + Diode is soldered very good.

Cons: - Flat MCPCB ; - Small ironing fields ; - Get very hot @ 250mA; - Light a bit to white, but it`s 7000K so it`s OK I have no more cons for this.

Other: Buy it!
