new zylight z90

[themagickite]

4 times brighter than z50

looks impressive, but i really have no idea how bright the z50 is anyway

sure does look cool though

got an idea of how bright the z50 is now
after looking at these charts

the last one is the only one i've worked with.

so if the z90 is 4x the z50 then it should be about half the lowel (when in flood) at 1.5 meters, pretty good considerring it's large even spread.

i wonder if they will release a small non-battery powered mains light, like an ianiro gulliver

Yeah, the new Zylight looks great; they went from the BL3000 LED engine (discontinued by its manufacturer) to the newer "Titan" engine. Should be a sweet light!

Litepanel mini flood puts out more than 2x Zylite 50.

3FC @6' Zylite 50

I'll wait for the z90. I wouldn't compare LED lights to lowel pro light. apples vs oranges.

Not so fast, the Z50 has a beam angle of 160°; you are only listing end-footcandle withgout taking the beam angle into account.
The Z50 "puts out more" light than the one you mention, but it does it over a wider area, so the end-footcandles at any given point may be less, correct.
Z90, by the way, is slightly narrower, but not by much.

Total lumen output of the "older" Z50 is about 300lm, and almost 900lm for the Z90 (with a slightly narrower beam; approx. 130° vs. 160°).
The Z90 is the brightest LED on-cam light by far, I'd say (of course it also uses much more power than other lights at full brightness...).

well i was just using those charts to get an idea of how bright "x" amount of foot candles is, and put them here in case anyone else was interested in the comparison.

i've just recently shot some stuff with the lowel which turned out great, but my uni has it hooked up to a small car battery, so it gets pretty heavy and cumbersom, also it only lasts about 1/2 an hour, and it's brightness falls rapidly within that time.

monkeyking, i can understand that led and somthing like the lowel are very different, but as i've only used the lowel i'd like to hear how?

is it just beam angel and even spread vs spot?

vidled, are you guys gonna make a new model too? or does this not really afffect you guys as you have much better prices?

My comment immediately above (or below, depending how you have DVX user set-up) was in reply to monkeyking's post, not yours. Sorry.

Yeah, that pretty much sums it up. There's a few criteria, and physics dictates their interrelatedness:
1) Weight
2) Size
3) Brightness
4) Cost

We are content with what we offer; as are our customers.

MK,
lowel pro light (I own 2) is a single point source enhanced by a focusing reflector behind the bulb . That reflector adds a lot of "punch" to the light - from flood to spot patterns. Hence, you can get a lot of light further away by spotting /focusing the beam of light.
LED lights brightness drops rapidly within a short distance. No adjustable beam spread. LED lights are good for close work especially as fill light. Look at the charts, see how footcandles/lux drop dramatically as distance increases.

I keep thinking that one of these nights I'm going to show off my vidleds... then once it's dark I start thinking more about bed time then video... but the point about the spread of the light is a major thing to consider... I love the wide swath of illumination that pours out of the vidleds. A lot of on-cam lights show the edge of the beam, and reveal that it's obviously an on-cam light... unless you zoom way in. Being able to use a light like this and still shoot at wide angles is really nice.

The other thing about all these lights that you may want to consider is how functional they are as OFF-camera lights. I made some little mounting plates so that I can use my vidleds on stands.

my comment was also a response to monkey king, nevertheless i was not offended by either of you.

the amount of spread is a good thing for sure, you may not be able to be as far from your subject, but if you don't mind the focal length distortion, you can shot in extreme wide to get well lit mid/long shots (not that i've tried it out myself, just guessing)

in my shoot with the lowel we used 2 in a pitch black park, in full spot mode, i can't imagine using anything weaker given our circumstances. but we we're using an mx500 which has 1/6" CCDs which wouldn't be ideal for low light but (although it pains me to say it) i have little to no experience with other cameras (apart from super8, but never tried any night shots) so i can't really make an informed judgement about it's low light performance. keep in mind we we're strictly not using any gain.

do LEDs provide enough light to give you some room to move around in (creatively and physically), on larger sensor cameras like the dvx100 (that is supposed to offer good low light performance)?


when using multiple lights right next to eachother (as one light source) do you get double the FC output? with the same rate of drop off?

lights, lights, lights.... so many questions.....

Matt, your video made me what to pull my two Cool light Vidleds out and play with them.

Love your little intructionals. Make more and we will buy them!

[MattinSTL]

Thanks Kelly... I moved that post to the Vidled thread for people that may search Vidled... it belongs there more then in a Zylight thread.

I'd hope the vidled guys would consider doing a really big panel like litepanels 1x1 for a reasonable cost. Knowing what I know about leds in electronic projects, their pricing is beyond reason.
