Are there specialists in road signage?

Question at 150 € / year: red lights with energy saving bulbs; possible?

At the exit and at the entrance of my taf are 2 bicolor traffic lights (red green) whose bulbs are simple incandescent bulbs 220V55W special signaling (I do not know what they have special but if we puts normal they slam quickly) These lights are on 24/24 (slaved to the automatic gates which must remain powered otherwise they open) it passes about 200 vehicles / day so the red bulbs are extinguished 200fix / day for 20seconds and are on the rest of the time the green are on 200 times / day for 20 seconds.
In the 5 years that these lights have been installed, the green light bulbs have never been changed, on the other hand we change 10 red light bulbs per year (around 12 € incl. VAT each).

Do you think that the replacement by a megaman E27 compact fluorescent is possible for the red bulb?

In addition these fires hit full in the sight of irascible truck drivers who wait for their turn ... I tell myself that a bit of light therapy could only be beneficial to them. In addition 2x11W instead of 2x55 for 22h20 / day ... I am awarded a medal and I go to TF1 in this is my land

What do you think gentlemen and ladies ????

Good eco-friendly suggestion!

Ah, do incandescent red lights still exist? (I thought leds were the norm for 10 years but your red light may be older).

This wear asymmetry is quite normal:

The green is on 400 h / year
The red the rest of the time is about 8400 h / year.

A priori there would be no contraindication to replacing the red bulb with a megaman ingenium since it will be hot and therefore bright from the start and they are resistant to repeated ON / OFF (ingenium technology)

See also the green but the power on ignition may not be in the "standards", so maybe see a more power bulb like for example: https://www.econologie.com/shop/eclairag ... ique-c-100 of 23W which will necessarily give more lumens when switching on than a 11W bulb

On the temperature side, the ingeniums are given for -10 ° C to 40 ° C, on the red it should be fine, for the green in winter, must see ...

In short, you have to give it a try ...

Otherwise instead of fluo, can be on this model of led bulb that lights like a 60 / 70W: https://www.econologie.com/shop/ampoules-led-c-90 (at least for the green bulb)?

ps: where does the figure 22:20 per day come from?

22:20 pm is 24 hours minus the 200 30second exctinctions (between the start of my message and the end of the post I have timed the extinction time the tempo is set at 20 seconds but the time that a semi-trailer starts and passes the barrier closure detection is 30 seconds depending on the irritability of the driver )

Incandescent lights are still in force in the private sector ... these devices are even from high quality German supplies. To have the equivalent in led it was necessary to multiply the price by 2 (but they only consumed 10W for 128 leds). As in more it is a sector of activity brought to disappear quickly one understands that my leaders do not see the savings in the long term. I have my back to do the paperwork necessary for a change of bulb on a seveso2 site

[Christophe]

I suspected it was 200 * 20 seconds but it didn't fit at 22:20 pm ...

Anyway if one is not on, it is the other. So you have the equivalent of not 2 but 1 * 55W over 24 hours all the time ... Except when the factory is closed? But I think it never closes a refinery ...

If in led the price is only half, I do not see pkoi deprive itself! Payback in a few weeks (less taking into account the human time to replace / order the bulbs that snap ...)

Ah indeed if the bulbs must be "compatible" seveso ... I understand better their price ...

[Macro]

There are two blocks of 2 lights therefore 2 * 55w permanently lit on the site. that of the green lights hold .. We are not going to buy back .. Even so .. And the led lights cost us double the purchase without guarantee of a longer life (at the time)

these are not seveso bulbs but sylvania signaling bulbs ... The prices range according to the supplier from 9 € to 15 € HT per unit ...

I'm just thinking of the captivity of this kind of market ... (administrations, sncf ...) or purchasing managers have never looked into the price of this crap ...

[elephant]

In fact, for a purchasing manager, he sees the budget he manages: as long as he has not received any orders, he is going at the cheapest: energy is not his business!

Only a few very small or very large firms allow themselves this kind of calculation: I remember one day having made an estimate for a large steel group: 20.000 euros.

The system saved 2 or 3 guards and a vehicle, so faced with the report of the security chief, the budget was granted.

FYI, in town, I saw new lights with LED bulbs.

And it even seems to me that in the old "blocks", they now put LEDs ...

I think the goal is durability (less maintenance; it is to move a snowman immediately - for safety reasons - which must be expensive, not the bulb) more than consumption ...

[dedeleco]

Good quality LEDs have a lifespan of 50000 to 80000 hours, some, whatever the number of switching on and off, even ms, provided that their T is as low as possible !!! (checked at home even on low-end LED)

The difference in overall cost is huge, purchase more use, so that all red traffic lights are expensive to purchase but very economical in terms of personnel and consumption (change 50 to 80 times less often, very increased safety, consumption in energy 10 to 20 times less !!).

So it's c ... not to use them in private for signaling functions comparable to the public, which has understood its interest for a long time !!!!!

[elephant]

I even know led's which have more than 225.000 hours of service (indicator light for the presence of voltage on alarm panels)

But, there is nothing to do, industrial buyers are indecisive and still too often held by "their" budget. That's what matters to their careers: getting the job done with as little money as possible.
Well, of course, if that allows f ... a guy at the door, they have the budget right away (or when it's the cross and the banner, + the hydraulic platform for maintenance)

It is very common that one waits for one in four lamps to be out to order the "relamping" work.
