dome question from a newbie

[bj]

Could someone explain the difference(s) between high and low dome emitters on the LS lights? Advantages/disadvantages of each? I'm considering purchasing a used LS and want to be clear on what to expect and how the emitter design affects the performance/price.

Thanks!

I think most of that info is right there.

Hi BJ,

Welcome to CPF!

Here are some helpful links on this subject:

[*]LSH vs. LSL - which do you like better and why?
[*]Perceived Brightness, LD vs HD [/list]

Hope this helps,

for a simple answer...a hd will result in longer throw and a squarish beam, whereas a ld will result in a round and better beam for closeup work.
also, hd luxones tend to be brighter and whiter than ld's.

my suggestion...get an arc lsh-p /ubbthreads/images/graemlins/grin.gif

Thanks all, it was late and I just wasn't finding it using the search. The part numbers (LSL, LSH, -P) make more sense now. Sounds like the high dome generally has better color and more throw, while the low has less controlled color and a wider beam. Appreciate the help, and tolerating a question that has probably been asked many times.

Get the high-dome (LSH-P). The low-dome LEDS are too much of a crap shot to try and get a good one.

Why is it that the color is better for the HD?

the hd luxeons use a different phospher applying process that the ld's do not. i'm not sure if the se's do, but my guess is yes, because the se's i've seen were pure white!!!
i really don't know why they don't use the process on the ld's...i'm not sure if anyone knows /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/icon3.gif
