how long would a 35 watt bulb last at 75 or 100 watts

do the 35 watt bulbs go snap crackle pop at 100 watts.

Not very long, I would not even try it.

 

[markdi]

why not

the bulbs are transformer coupled arn't they ?


I would have to have a schematic to figure out how to do it - and 2 identical ballasts. (or more - to give up magic smoke to the electron god's ha ha)
- get rid of one of the igniter circuits - etc.
- run both ballasts from a common clock - who knows ?

a clean workspace with no alky sister and kids would be nice.

why not? The 35 watt bulb life will go down radically at 70-75 watts let alone 100 watts. The DL50 has thicker quartz around the arc envelope to handle the increased pressures. Running a 35 watt bulb at 50 watts is one thing, 70-100 watts is quite another.

The bulbs are transformer coupled arn't they? Flyback transformers are used.

After the initial arc strike, the power output control circuitry depends on monitoring the bulb impedance to control proper voltage and current output. maintaining a steady 35, 50 or 75 watts. Some ballasts use a digital preprogrammed algorithm to control output power. You definitely don't want to consider using 2 of those to accomplish this. If I know the brand I can probably tell you if it is digital or Analog. If you could do this at all, you will need to have only one control circuit to manage the whole system.

I would have to have a schematic to figure out how to do it - and 2 identical ballasts. None of the manufacturers is going to provide you a schematic (or more - to give up magic smoke to the electron god's ha ha)
- get rid of one of the igniter circuits - etc. Yes, that would be true.

I know quite a bit about hid ballasts

I may not be on your level but

I have looked at the output waveforms of my 35 watt ballast and my25/50 watt xenlight balast on my tds 3054.

boy I wish I knew where my wave star software disk was.

there are a few circuit diagrams floating aroun the net

one is for a hella ballast

another is a home brew 50 watt ballast.

quite a while ago some one posted a link to a manufacturer that had 12 volt balasts up to 150 watts or so - not just for d2s aplications(before the great change - cpf transmortifacation)

I have looked at the output waveforms of my 35 watt ballast and my25/50 watt xenlight balast on my tds 3054.

I prefer an anolog scope for realtime performance. I use a Tek 2465B 400 MHz and 2465 300 MHz. I also have an inexpensive Instek Digital (color) scope which interfaces to my PC.

Have you tried puting a current probe on a wire to the bulb from the igniter from the Xenlight unit to see how stable the current is when you shake the bulb. It should be very constant power.

 

[markdi]

does your 2465b have the micro channel crt(bright eyes - exspensive option) and the acquisition pack ? mine does.(needs a new hard drive)

I worked as a tech and a calibrator(before cat's - computer aided test system)) on the line that made them.

I got a big award for not making 1 verifiable mistake in 9 months.

 

[markdi]

one of my more interesting scopes is a 2252
with Scrolling vector graphics

the scrolling part never made it into production

I got it from a tech I carpooled with.

he got tired of me borrowing it from him so he gave it to me.

less than 1.1 minor divs(subtracting trace width)
aberation at 130 mhz

last time I checked it any way.

The only special fearures my 2465B has is GPIB.

Sounds like you are good at what you do.

These scopes are just "tools" for me. I only use them for very specific tasks. They are not utilized by me for much of their true capabilities. I only know how to do some very specific things with them. I have other people who are the capable users.

 

[markdi]

it would be kol to have a gpib card in my pc.

I would probably never use it - still it would be kool

the 2400 series are the best portable analog scopes ever made.

tds 5 6 and 700 series are realy nice

the 7000 and 8000 series are kool - exspensive and not very portable.

I do not work for tek any more.

I am between jobs.

there is a small chance I could be re hired in 6 to 10 months.

I can not wait that long.

I have cerebreal palsey - it makes job hunting a little harder.

I have cerebreal palsey - it makes job hunting a little harder. I can only start to imagine. Are you forced to use a wheel chair?

 

[RalphRussell]

As of a few minutes ago, a Group Buy from "ZEE"Vision has been started for dI50's (also known as Barn Burner Bulbs). It will last until 2/10/06.

 

[markdi]

no wheel chair

motor dis function in right hand

I kinda walk with a limp - right leg

I can out run any of my friends my age that smoke.

not too bad.

could be a lot worse.

still I think I will tell employers that I injured myself in a motorcycle accident.

I think telling them I have cp kinda scares them.

Could be a problem with insurance coverage if the employer offers it.
I imagine it does limit your opportunities.

 

[XeRay]

I have changed my CPF name to a more specific and relevant one. My name is now XeRay since that is the name of our Searchlight product line. XeRay-35 (35 watt), XeRay-50 (50 watt) and XeRay-BB (75 watt).

I will be at the Shot Show Friday Morning-Saturday afternoon for those who will be attending, I look forward to meeting you.

[XeRay]

All group buy BB bulbs have been shipped via insured UPS today. Depending on your location, (distance from Utah) you will receive them between Wednesday this week and Monday Next week.

The only exception is "Mad Maxabeam", he has not paid yet.

 

[XeRay]

Mad Maxabeam, I will hold your bulb purchase spot through this Friday at 17:00 hours Mountain Standard time.
