High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens.<ref>{{cite web |url=http://www.luminus.com/content1044|archive-url=https://web.archive.org/web/20080725033952/http://www.luminus.com/content1044 |archive-date=2008-07-25 |title=Luminus Products |publisher=Luminus Devices |access-date=October 21, 2009}}</ref><ref>{{cite web |url=http://www.luminus.com/stuff/contentmgr/files/0/7c8547b3575bcecc577525b80d210ac7/misc/pds_001314_rev_03__cst_90_w_product_datasheet_illumination.pdf |archive-url=https://web.archive.org/web/20100331100545/http://www.luminus.com/stuff/contentmgr/files/0/7c8547b3575bcecc577525b80d210ac7/misc/pds_001314_rev_03__cst_90_w_product_datasheet_illumination.pdf |archive-date=2010-03-31 |title=Luminus Products CST-90 Series Datasheet |publisher=Luminus Devices |access-date=2009-10-25}}</ref> LED [[Power density|power densities]] up to 300 W/cm<sup>2</sup> have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from an HP-LED is not removed, the device fails in seconds. One HP-LED can often replace an incandescent bulb in a [[flashlight]], or be set in an array to form a powerful [[LED lamp]].

Some HP-LEDs in this category are the [[Nichia]] 19 series, [[Lumileds]] Rebel Led, Osram Opto Semiconductors Golden Dragon, and Cree X-lamp. As of September 2009, some HP-LEDs manufactured by Cree exceed 105&nbsp;lm/W.<ref name="Xlamp Xp-G Led">{{cite web |url=http://www.cree.com/products/xlamp_xpg.asp |title=Xlamp Xp-G Led |website=Cree.com |publisher=[[Cree, Inc.]] |access-date=2012-03-16 |url-status=dead |archive-url=https://web.archive.org/web/20120313082324/http://www.cree.com/products/xlamp_xpg.asp |archive-date=2012-03-13 }}</ref>

Examples for [[Haitz's law]]—which predicts an exponential rise in light output and efficacy of LEDs over time—are the CREE XP-G series LED, which achieved 105{{nbsp}}lm/W in 2009<ref name="Xlamp Xp-G Led" /> and the Nichia 19 series with a typical efficacy of 140{{nbsp}}lm/W, released in 2010.<ref>[http://www.nichia.co.jp/en/about_nichia/2010/2010_110201.html High Power Point Source White Led NVSx219A] {{Webarchive|url=https://web.archive.org/web/20210729062935/https://www.nichia.co.jp/en/about_nichia/2010/2010_110201.html |date=July 29, 2021 }}.
