Replacement LED ceiling light, Translation please!

I bought a replacement LED ceiling light. I already removed all the fluorescent fittings ballast and starter and was hoping this LED would be a easy fix with mains wires straight into the new fitting.

 

Unfortunately the new LED light has a 4 pin adapter, like for a fluorescent so not sure if it will work by just two wire connection to the mains.

 

I Found a YouTube clip which shows how to connect my LED but it's in Thai and not very clear.

 

In the video clip the guy seems to say that the LED will work with the ballast and then looks like he disconnects the ballast and connects the LED directly into the LED. Seems to indicate that the Light will work with or without the old fluorescent fittings.

 

What I need to know is can I connect the light straight to the mains or does it need to be wired through the old fluorescent ballast and starter. 

 

The wife got confused with all the "technical" speak so wasn't much help with translation what the guy said in the video clip, so am hoping kind soul could listen to the clip and let me know if I can connect straight to the mains without things going bang!

 

Thank you

I bought a similar replacement ( from fluorescent to LED ) and the instructions told me to remove only the starter and retain the ballast.

Have changed around 5 and they all work fine.

 Flickering on start up used to drive me nuts !

He says there are two ways to connect. The first is simply to swap the old tube for the new LED one. Plug in the new tube but remove the starter otherwise the light will flicker. 

 

The second way is to disconnect the ballast and wire the new tube direct to the wires that were going to the ballast.

 

First option seems much easier. Plug n play.

 

PS - when I changed old starter/ballast lights for LED I just bought new LED complete sets and got rid of the old ones completely.

Thats what I was hoping for.

 

As said in my original post I had already got rid ballast and starter, so have no choice but wire it direct to the mains.

 

Just a thought, does he say anything about the polarity of the wires, does it matter ?

 

Thanks

Doesn't say. I don't think it matters for a plug and play LED light. But I'm not an electrician,

Update:-

 

The light can be wired direct to the mains, bypassing all the old Fluorescent fittings.

 

And no, polarity doesn't matter

      Not only expensive but fragle compared to the Dynamic mics. I think some of those Shure mics could be run over by a truck and used to bludgeon an unruly audience member and still work fine. 🤣

      What is AIS/3BB Fiber router super-admin password? Want to make HG8145X6N back into an AP

      WHEW after a LONG search of mostly Thai posts from AIS customers on random Facebook Groups, I was able to crack this one. The old username/password super-admin combo username: awnfibre password: fibre@dm!n still works, but they have thrown another bit of security by obscurity into their totally insecure system of ISP backdoors compared to earlier Huawei AIS/3BB modems. Like many Chinese modem brands shipped and configured by South-East Asian ISPs, the unit is riddled with plenty of other insecure backdoors too, like TR-069 with a hardcoded password. Anyway, let's say you just reset your HG8145X6N (and it looks like you may need to have the reset button pushed down already when plugging in the power, and hold it for say 20 seconds after turning on the power and before releasing it in order to get a true reset that really restores default configuration, rather than just poking the reset button while the unit is running) and it has lost AP mode capability. Or, let's say you have a HG8145X6N that was being used before as your main router/ONT with the fiber connection (or used to connect to a fiber modem over the LAN4 ethernet port via PPPoE) and you want to re-purpose it as an AP to extend your network (hopefully via wires from the main router: wireless repeaters are universally terrible). To get the unit (back) to AP mode: 1. first, without the HG8145X6N connected to anything else, connect your computer to the HG8145X6N by an ethernet cable and log in to the HG8145X6N's admin GUI using the less powerful admin/aisadmin user/password combination. You access the admin GUI with a browser and you can get the HG8145X6N's admin IP address by running 'ipconfig' in a cmd.exe window or seeing what gateway your computer has gotten by DHCP from the HG8145X6N (typically 192.168.10.1 in my experience, but could be other). In the admin GUI, go to the LAN configuration tab. You need to change whatever admin IP address it chose (e.g. 192.168.10.1) to an IP address of 10.207.247.1 and change the netmask to 255.255.255.0. Click OK/Save/Configure and allow the router to reboot and allow your computer time to get a new IP address on that subnet via DHCP. This combination assures that your computer's client IP address will be 10.207.247.x. From experimentation, it appears that only 10.207.x.x or perhaps even only 10.207.247.x will allow the next step to work (sigh, security by obscurity). 2. Now, log into the HG8145X6N admin GUI again (this time at 10.207.247.1) and this time use the super-admin username/password combination awnfibre/fibre@dm!n so that you gain access to a lot more options. If you did step 1 properly, you should be in. If you didn't do step 1 properly, you will get a login error message "You IP address cannot be used for a login." (or you'll get a blank screen due to their buggy software, and if you hit the browser back button then you'll see that error message in red). Once you're in, spend some time seeing all the useful options your ISP was hiding from you. Now, when you click the "mode switching" menu at the top right, you will see that there's an option for AP mode that you can choose. Choose that and this will cause the HG8145X6N to reboot again. 3. Now the next step depends on whether your home/business setup uses all Huawei routers with their magical auto-configuration of APs, or not: 3a. if you're using all Huawei routers, then plug your HG8145X6N via ethernet cable to the main router and it should magically join the big network and automatically configure its own IP address as well as automatically use the same wireless SSIDs as other routers on your network (this happens because of the default-enabled option "Basic Setup...WLAN... Smart network connection" on the HG8145X6N). In theory you should be done. Now you mostly use the Admin GUI of your main router, though from that GUI under "Home Network Status" you can click to access the (now much reduced) admin GUI of the HG8145X6N that you just set up. But you'll probably never need to configure any of the APs individually. 3b. if you're not using all Huawei routers, then you'll need to configure your HG8145X6N as an AP manually. Use 'ipconfig' again to find the current router IP and log into the router admin GUI using the less powerful admin/aisadmin username/password combination. From here, you may or may not have enough access to configure everything you want. For sure, you will be able to choose LAN address and wireless SSIDs. But when I looked through the menus, I didn't see a way to make the HG8145X6N fetch a WAN IP address via DHCP from an upstream router (the unit ALWAYS wanted to treat either its optical port as the WAN or look for an optical device on LAN4 ethernet that it could connect to using PPPoE and then treat that as the WAN). And I also didn't see any NAT/Firewall options. However, it could simply be that "AP Mode" does exactly this already (NAT to an upstream WAN whose IP it fetches from DHCP) and so there is nothing to configure. If you don't have enough control, you might have to repeat step 1 again to change the admin IP back to 10.207.247.1 again to regain access to awnfibre/fibre@dm!n so you can make the settings you need. I'm not 100% sure that the HG8145X6N is even capable of operating as an AP (with an ethernet WAN, as opposed to an optical WAN) without the proprietary Huawei stuff in (2a) above. However, I didn't spend time exploring the expanded setup menu choices offered by awnfibre/fibre@dm!n. Either way, now your router is up running in AP mode (looking in "Status...Device Information" you will see the device again identifies itself as "OptiXstar HG8145X6N Repeater Terminal"). Good luck!

      The big mics you see are condensor mics. Expensive. They are used for most high-end professional recordings because of their quality and frequency response. Dynamic mics are 7x cheaper, mostly used for live events. As a musician, I can disagree and say those clip-ons are horrible. I have produced many videos. It takes me so much time in post production to get them to sound good without the speaker souding like an amateur.

      Beachside bungalows Koh Phangan.

      Hi all, buddy and I take a guys trip for a couple of weeks somewhere on the islands each year to get out of Chiang Mai and away from family life. Remarkably, we just realized neither of us have ever been to Koh Phangan. We are looking for rustic beach side bungalows similar to White Sand Beach resort bungalows on Koh Chang. We have spent a chunk of time looking at resorts online but would love to hear some personal experience recommendations if you don't mind. As always, thanks in advance!

      Boeing's Kiss of Death: What is needed now is an engineer to take over?

      You see, FOLKS.... Boeing is no longer.... Hard enough Rough enough Tough enough Smart enough Rich enough... To be successful. ENGINEERING IS HARD. THE NATURAL SCIENCES ARE HARD. No BEAN COUNTER can ever measure up. Yet, Boeing is now being lead by guys who are soft as .... American Baked Beans. Just mushy....down deep...inside. Just mushy. And, mushy is the right word for Boeing, these days, compared to.... The 60s, when we had REAL MEN leading this important company. I am ashamed. Not for myself. I am ashamed for what Boeing has become. Engineering is HARD. We need a HARD MAN at the helm to guide Boeing back to.... What this great company was always meant to be. If not MUSK...then.... Who? Me? NO! But, there is a MAN for the job....SOMEWHERE..... We need to find him, maybe on TV? NO! But, somewhere..... Somebody, a MAN, who is HARD..... A hard man. That's what we need..... ================ Pretty, Pretty, Pretty, Pretty...PRETTY girl.... Come home to me......
