Now the XML2 can put out nearly 1500 lumens at 6A with good heatsinking. xml_find_first() now always returns a single node: if there are multiple matches, it returns the first (without a warning), and if there are no matches, it returns a new xml_missing object. The conductivity of FR4 (commonly used PCB material) is about 1400 times less than copper, and about 700 times less than aluminum, so even a very thin layer has a big Forum FAQ Calendar Forum Actions Mark Forums Read Policies & FAQs CPFClassifieds Underground CPF Supporter CPF Facebook Group Advanced Search Forum Beyond Flashlights LED what's the difference between XML vs XML2
Follow To Us Subscribe for everyday tips & tricks of use R for data analisys and data science! Operations on xml_nodesets are vectorised, apply the operation over each node in the set. The basic process of creating an XML document by hand looks something like this: root <- xml_new_document() %>% xml_add_child("root") root %>% xml_add_child("a1", x = "1", y = "2") %>% xml_add_child("b") %>% The XM-L2 LED offers the unique combination of high efficacy and high lumen output at high drive currents, delivering an unprecedented 1198 lumens at 116 lumens-per-watt efficacy at 3A, 25ºC.
Not in South Africa, but someone here (vestureofblood I believe?) is selling them for extremely reasonable prices, with only a couple of bucks shipping anywhere in the world. This bonding was a bottleneck. You may have to register before you can post: click the register link above to proceed. The difference stated by the manufacturer is roughly 20% improvement.

To be more specific, it isn't just the bonding, it's the thin layer of fiberglass insulation (it's actually a very thin circuit board) that causes the thermal 'bottleneck'.

Cheapest source is probably from computers, see if anyone isn't using their powermac anymore PS. Sounds awesome Yes. 'tis. Support for modifying and creating xml documents in planned in a future version. The theory (and seemingly tests bear it out) is that there is a much more direct and unrestricted thermal path which goes directly to a copper heatspreader (the board), meaning you
How fast do u see these LEDs evolving, maybe 1 level of improvement per year? Like the SolarStorm that we have how great would it be for that to handle the heat continuously?

This includes new functions xml_new_document(), xml_new_child(), xml_new_sibling(), xml_set_namespace(), xml_remove(), xml_replace(), xml_root(), and replacement methods for xml_name(), xml_attr(), xml_attrs() and xml_text().

If its working for you, you're done.
Also, the bond wires are still there, in fact instead of 3 of them there are now only 2 which is the probable reason for the Vf of the XM-L2 being Xml2 is a wrapper around the comprehensive libxml2 C library that makes it easier to work with XML and HTML in R: Read XML and HTML with read_xml() and read_html().

Your cache administrator is webmaster. does XML2 have tighter spot ? Don't want them trying to land.

If you want a light that's smaller but the same performance, or, find it WASN'T working for you...then get a better light when available, and so forth. And hopefully XML3 will be 20% brighter than XML2, than XML4 will be 20% brighter than XML3...

I think it's a good upgrade. All comments are reviewed prior to being posted to ensure appropriate language and content is used.

Good manufacturers of anything ALWAYs intentionally underrate their products, i.e. Built on the SC³ Technology™ Platform, XM-L2 LEDs are available in white, 80-CRI white, 85-CRI white, and 90-CRI white.
