What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates.

Pros: These things are much smaller than i thought they were and are insanely bright for how bright i thought they would be
It would be awesome if they were cheaper, but i believe DX is offering the best deal for them right now.
 
Cons: Even better if they were cheaper.
 
Other Thoughts: There about the size of a quarter and get somewhat hot.
Make sure you have them attached to a heatsink or a think piece of aluminum to dissipate the heat.
You'll also need some cheap thermal grease to make the best connection.
 
Bottomline: BUY THEM.

Bright light, perfect for modding

Pros: Bright cree emitter on star, perfect for modding bike lights and flashlights etc. Allows you to build your own lights for cheap.
 
Cons: May require filing as mentioned in other reviews to fit into a lot of flash lights / torches. You need to be able to solder the star so some skill is required.
 
Other Thoughts: Could always be cheaper but for the price this is hard to beat on here.
 
Bottomline: Extreme deal. I would buy again if I needed to do more modding.
Buy this and mod your own lights instead of paying ridiculous retail prices for commercially available options.
I used this with a cheap flash light from here and the plastic holder to attach to bike handle bars. Gold.

Pros: ~ Brightness
~ Price
~ Aluminum PCB makes heat transfer easy
 
Cons: None
 
Other Thoughts: Amazing deal people.
I would put a "no more comments" here, but I'm obliged to give a 500 characters explanation of why I recommend these leds.
Well, for one thing the price is amazing and with the "no-shipping-fees" policy of DX you can't go wrong.
Secondly, I wanted a bright bicycle light for my night commutes, but had very few money and I didn't want the 10$ weakling lights that are all over. For less then 25$ I have built a two-led, super-bright bicycle light comparable to 100$ products.
Finally it was easy to build due to the star PCB that makes pairing to a heatsink a breeze. Then I got those cheapo-but-ok lenses from here (SKU 1920) and woila. Bicycle light ready.
 
Bottomline: Highly recommended.

Pros: Ahhhh, it burns your eyes cause it's so bright!!  Brightest 1 Amp, 3.4 V chips I've seen!!  Paired with the other DX lens it is an amazingly tight & perfect  beam.  For a good price.  Not hands down smoking deal, but for the quality, and with the free shipping ...is a pretty darn good deal.  You would be hard pressed to get the same price at a low volume that's for sure.
 
Cons: None really.  Would be nice if this same chip was on a small circular base.  Many of the other on tiny 16/18mm sinks are lower Lumen bins, therefore not good for me ...or you maybe?
 
Other Thoughts:  
Bottomline: Get them while you can!  Buy at least the min, and pair them up with the 10 deg 5 pk DX also sells, sku#01920
