Build thread of my 55w HID spot Pics Added

Just a quick question.

How hot does a 55w HID lamp get will it melt a plastic reflector?

Thanks lovecpf

Re: Will plastic reflector melt?

If you pack the reflector in dry ice or liquid nitrogen and use the light only at the South Pole at -60degF in a 100mph wind on the 1st Sunday in June when there's a full moon, it should be OK. Otherwise, I think it might melt, lol.

Apologies Andredt2863 - that was a facetious comment of mine. However, 55W of HID does belt out a lot of heat! You should see what a 40W one did to my mouse-mat when I stupidly left it on head down.

ROFL no probs bud at least you're answer made me laugh.

Thanks buddy.

Re: Will plastic reflector melt?

From ure statement i presume a 55w HID will get hotter then a !00w halogen.

Re: Will plastic reflector melt?

The 100W halogen will actually be much hotter, as it is a less efficient light source - more of the energy output is heat.

Re: Will plastic reflector melt?

U see the light im using as a host currenly got a 100e halogen lamp in swapping it with a 55w hid lamp and digital ballast.

Re: Will plastic reflector melt?

The 100W halogen is probably operating at ~30 lumens/watt, and the 50W HID at maybe 100 lm/w. The HID is ~3x as efficient.

My guess is you are using a big and fairly shallow-profile reflector (>6" diameter?) and the lamp is physically further away from the reflector surface than would be the case with a smaller and deeper reflector.

I'm not sure how 100W of halogen isn't melting it, but it obviously isn't, so maybe there's hope for this. It will depend on how you mount the ballast etc - and for that I would prefer one of the HID experts here to comment.

Good luck with it - and let's see some photos!

I don't know how hot a reflector gets, but on any of my HID flashlights, the glass lens itself bakes at a toasty average temperature of 350 degrees fahrenheit.

Re: Will plastic reflector melt?

Depends on the reflector material and the coating i guess.
I have a 50W HID running in a plastic reflector that does only get warm,
even with long runtimes.
But i also melted one with only 35W in about one minute.
Was actually funny to watch the beam pattern changing until i
realized what was happening,

Re: Will plastic reflector melt?

I'd say it's risky even though the halogen hasn't melted it yet. With HID your runtimes will increase a lot and that could be the only thing that was preventing the halogen from causing a problem. 100W halogens only run a very short time with rapidly decreasing output on a 12V 7A SLA. If the light is inexpensive and or the reflector is replaceable then I'd say go for it. Otherwise you might want to save your mod for a more suitable host.

Re: Will plastic reflector melt?

Are you sure it is plastic? I can't see a manufacturer putting a 100W halogen in a plastic reflector. Do you know the brand/model of the 100W light?

Re: Will plastic reflector melt?

I have a Lightforce SL240, It has a plastic reflector, and plastic lense, and puts out a lot of heat, and it uses a 100w halogen, and it can be left continuously on without melting

Theres plastics and plastics

I know NOTHING about HID though..... so as for answering your question i have no idea...

 

[Patriot]

Re: Will plastic reflector melt?

Wow...the SL240 has a plastic reflector!?

I've got a Blitz240 and it as a metal reflector but a plastic lens, which even that surprised me.

Re: Will plastic reflector melt?

Ok guys i made a mistake the reflecter looked like plastic but when i took it apart it was infact metal.



The two 6v 4.2a batteries.



The 55w 6000k ballast



The H3 HID globe



The reflector.



Reflector back.



The host light.



Inside of the host light (nice and spacious.)

 

[Andredt2863]

Re: Will plastic reflector melt?

The ballast and light is top quality straight from taiwan :nana:

It is a 55W 6000Kelvin unit in H3 form so bulb wise it will drop in directly just need to mount the light.

I made a mistake and thought the batteries will become 12V 9amp as it is two 6v 4.5A cells.

Norm explained to me this is not true.

So i will replace them soon with a 12V7A unit.

I need to figure out how i will install all this and put a new switch in.

Please note i will document all steps as i go.

Lastly i stick the globe into the reflector last night and connected the wires straight from the ballast to the batterie, just to see how it will look.

AND IT WAS EXTREMELY BRIGHT. when i stand on my balcony there is a house up in the hill about 800m from my house and it lit it up beutifully. Threw a huge white circle on the house.

PS Any advice comments or help will be appreciated.

Re: Will plastic reflector melt?

I Moded a light like yours with HID before I got another host here is the tread

Re: Will plastic reflector melt?

Forgot to say that I changed the host because the ballast and 7ah SLA did not fit inside the package and had to use a "Spacer" so everything could fit.

Nice job Andredt. I'll bet you're pleased with the performance!

 

[Andredt2863]

I will let u know that when im done Patriot

But i am also thinking it is gonna be the bomb :twothumbs
