Shouldn't the Arc Lamp be positioned in the 1800-ish position on the timeline instead of 1840? The technology happened in 1801, a general rollout of an implementation of it happened in 1840's paris. Dialate (talk) 00:31, 23 August 2008 (UTC)[reply]

What is the relationship of Henri Becquerel and A.E. Becquerel ?? dml

Alexandre-Edmond was the father of Henri. --Jose Ramos 10:01, 24 Sep 2003 (UTC)

What about energy efficient bulbs? Why aren't they on here. I would consider that a significant milestone.Prince.timotheus (talk) 00:41, 10 June 2009 (UTC)[reply]

I think energy efficient bulbs are encapsulated in the mention of their inventions (such as LED), and from there, history has just seen a lot of minute steps that are progressing them toward widespread affordability and use. —Preceding unsigned comment added by 158.158.240.230 (talk) 02:24, 19 January 2010 (UTC)[reply]

Requesting electrostatic luminescence (ESL) lighting history if anyone knows it. Aditya.m4 (talk) 22:28, 29 January 2010 (UTC)[reply]

Lots of recent history missing[edit]

There needs to be coverage on

- LED lighting (red, green, blue, white and possibly orange, yellow, violet, purple).

- Compact florescent is significant enough to warrant a mention separate from florescent.

- Glow sticks

- High Intensity Discharge (HID) lamps

- Krypton bulbs

- Xenon lamps

- possibly Black lights and germicide lights (on the other hand these are generally not meant to help humans see).

A lot of the articles referenced from this page actually have a list of other lighting technologies. I think the real challenge will be figuring out when each of them were invented. —Preceding unsigned comment added by 204.246.125.93 (talk) 04:13, 3 May 2010 (UTC)[reply]

For a moment I thought the same. However, LED is already there, I believe HID/Krypton/Xenon are just forms of incandescent, and CFLs were more of an electrical invention (the ballast) than light. What I do question being omitted are flares and fusees. --Juventas (talk) 07:06, 30 March 2011 (UTC)[reply]

Not in list[edit]

I was surprised to see technologies in the diagram not listed in the text, as well as vice versa. Tabby (talk) 19:08, 24 June 2011 (UTC)[reply]

Candles[edit]

The date given for invention of candles (3000BCE) differs significantly from that in Candle (200BC) and History_of_candle_making (300BC). Just saying. 87.112.134.87 (talk) 20:01, 12 June 2012 (UTC)[reply]

Invention of Kerosene Lamps[edit]

Kerosene lamps appear twice, once around 900 C.E. and then over 900 years later in 1853. Is it just that the earlier invention was cruder and was not well known in the West? Should we change the later date to something like "modern kerosene lamp invented" or "predecessor of practical, mass-produced kerosene lamp invented"? Darkstar8799 (talk) 16:35, 1 November 2012 (UTC)[reply]

Couldn't have predated the invention of kerosene, at any rate. What do the sources say? --Wtshymanski (talk) 18:30, 1 November 2012 (UTC)[reply]

citation needed[edit]

I think "70,000 BC - A hollow rock, shell, or other natural found object was filled with moss or a similar material that was soaked in animal fat and ignited." needs a citation. 24.17.19.29 (talk) 12:52, 25 September 2014 (UTC)[reply]

Insufficient Citation[edit]

The first technological date listed is "125,000 BC Widespread control of fire by early humans.[1]" which links to a Web 1.0 vegetarian page, not an archaeological source. Also, this claim is heavily disputed by the page: Control of fire by early humans This should be updated with accurate and up-to-date information. — Preceding unsigned comment added by ZonKonigin (talk • contribs) 23:45, 16 May 2022 (UTC)[reply]
