<p>If anybody on this Forum (or anybody you know) has purchased either a "Pro" or an "Ultra" microflash unit during 2014 from Laserscribe, Ely, Cambridge, U.K. (highspeedflash.com) could you please e-mail me on gregjparker@live.co.uk with details of the purchase?<br /><br />Many thanks,<br>

<p>I can't answer your question directly, but a new ultra-high speed flash is entering the market. An inventor, Matt Kane, from Bristol, UK, has developed an LED based flash that promises a sub-microsecond duration. see https://www.vela.io/ for more information. Because of the extremely short flash duration, the guide number is low, and therefore ambient light may overwhelm the flash unless used in a dark room or at night. So, using it for hummingbird photography may be problematic.</p>

<p>Parker Technology (Prof. Greg Parker) will be making a batch of high-power Xenon flash units for early 2016. Using a new capacitor and having spoken to a number of potential users the spec is:<br>

1) Light output power 100 Joules.<br>

2) Light pulse duration 25-microseconds (1/40,000th of a second).<br>

3) Recharge time <5 seconds.<br>

4) Size of flash head 230mm x 180mm x 165mm (deep)<br>

The flash head is powered by a 12 Volt dry battery unit also supplied with the head, a charger for the battery is also included.<br>

Estimated cost £2,000 plus VAT at 20% plus p&p.<br>

If you have any interest in this equipment contact Prof. Greg Parker on gregjparker@live.co.uk </p>

<p>I have an Olsen Ultra flash in excellent condition. I'm selling only because of poor health.<br>

Interested people should email me at home@gregscott.com<br>

It is powerful, has four flash heads, and is in excellent condition considering that it was made maybe 20 years ago.<br>

It has new capacitors (reworked circuit board)<br>

It is suitable for photographing raptors in flight on the flight path to their nest, for example. I used it mostly for hummingbirds, where it was pretty much overkill.<br>
